# The great filament

From Spaceweather.com with apologies to Linus and Charles Schulz

The Solar and Heliospheric Observatory (SOHO) is tracking an enormous magnetic filament on the sun. It stretches more than one million kilometers from end to end, which makes it an easy target for backyard solar telescopes. For the seventh day in a row, an enormous magnetic filament is hanging suspended above the surface of the sun’s southern hemisphere. The Solar and Heliospheric Observatory (SOHO) has a great view. How long can it last? Solar filaments are unpredictable. If this one collapses and hits the stellar surface, the impact could produce a powerful Hyder flare.

The most recent SOHO image is here

Hyder Flares: from Australian IPS 1. What is a Hyder flare?

Flares are intense brightenings that occur in the solar chromosphere. Flares are generally observed from Earth using narrow band filters, typically with a bandwidth of less than 0.1 nm, and often centred on the Hydrogen-Alpha wavelength of 656.3 nm. (Flares also have counterparts, that is, sudden outbursts, in the radio and X-ray spectrum).

Most flares occur around active regions associated with sunspot groups. However, occasionally a flare (sudden brightening) is observed well away from an active region or sunspot group. These flares are invariably associated with the sudden disappearance of a large (thick, long, ‘bushy’) dark solar filament, and are termed Hyder flares.

2. Why are Hyder flares so named?

Max Waldmeier wrote a paper in 1938 which described the phenomenon of suddenly disappearing filaments (disparition brusque), and mentioned that these can be associated with flare-like brightenings, but it was left to Charles Hyder to postulate the first comprehensive mechanism for the such flares.

Following on work from his doctoral thesis with the University of Colorado in Boulder (1964), Hyder published two papers in the second volume of the journal Solar Physics (1967) in which the mechanism by which Hyder flares might occur was discussed in detail. Hyder was then on the staff of the (US) Air Force Cambridge Research Laboratories at the Sacramento Peak Observatory in New Mexico.

It was these papers in Solar Physics by which Hyder’s name became associated with the flares in question, even though he was by no means the first to observe them.

3. What are the characteristics of Hyder flares?

As previously mentioned, the name Hyder flare is given to a flare that occurs away from an active region or sunspot group and that is associated with the sudden disappearance of a dark filament. The appearance of these flares can range from a string of bright knots on one or both sides of the filament (or rather, the position previously occupied by the filament, sometimes called the filament channel), to a single or double ribbon flare. The ribbons are parallel to the filament channel. If only one ribbon is present, it will lie to one side of the channel, whereas if two parallel ribbons occur, one ribbon will lie on one side of the filament channel, and the other ribbon will lie on the opposite side.

One interesting characteristic of Hyder flares is that they usually develop or rise to maximum brightness much more slowly than do the more common flares associated with active regions. The larger Hyder flares may take 30 to 60 minutes to rise to a peak intensity, and then they may last for several hours. Although they may attain a large area, they usually have a relatively low intensity. Thus, classifications for a large Hyder flare may read 2F, 2N or possibly even 3F. This contrasts to an active region flare in which 3F is very rare. An active region flare that attains sufficient area to put it into the importance class 3, will invariably have either a Normal or more usually a Brilliant brightness classification.

X-ray flares and radio (microwave) bursts associated with the optical Hyder flare, are also generally long lived phenomenon and are classified as the gradual rise and fall type of event (in contrast to the impulsive and complex events associated with large active region flares).

Generally Hyder flares are not associated with energetic particle emission or geomagnetic storms (implying that they may not be associated with a coronal mass ejection). However, this is not always the case, as a large halo CME observed by the LASCO solar coronagraph on board the SOHO spacecraft was most definitely associated with a Hyder flare (2N/M1) observed on 12 September 2000. This same complex also appeared to have produced energetic protons at geosynchronous orbit with energies in excess of 100 MeV, and in substantial numbers at energies of 10 MeV. It is believed that the sudden storm commencement observed at 0450UT 15 September, and the subsequent minor geomagnetic storm was produced by this particular CME.

4. What produces Hyder flares?

Hyder’s explanation of the flare type now named after him depended on the observational evidence that (1) often the flare was a parallel ribbon flare with one ribbon each side of the filament channel, and (2) that geomagnetic storms were not associated with these flares. This led to the speculation that the filamentary material was not ejected far into the corona, but in fact fell back to the chromosphere producing the flare.

Stable or quiescent filaments are believed to lie in and along a magnetic trough. It is thought that the sudden disappearance of such a filament is due to a reconfiguration of the field. In essence, the magnetic trough becomes a magnetic ridge (the bottom of the trough elevating in a period of tens of minutes to become the peak of the ridge). In this process, the filamentary material (cooler gas) is thought to be accelerated into the corona. Hyder’s explanation is that, in the case of the Hyder flare, some or even most of the filament material, instead of suffering acceleration and ejection, falls down the sides of the magnetic ridge and interacts with the lower chromospheric material producing the flare. If the infall process is symmetrical, then the double parallel ribbon flare will result, if asymmetrical, then only one ribbon results. If the infall is sporadic, or the material insufficient, then only bright knots of flare are produced. Hyder did calculations to show that the kinetic energy of the infalling material should be sufficient to provide the required flare energy release observed.

Of late, the Hyder mechanism has come into question. Some people (notably Zirin) have questioned whether infall occurs, stating that the magnetic reconfiguration must always produce ejection. The respective roles of flares and CME’s in solar active processes has also been hotly debated, and this has implications for the exact mechanism of Hyder flares. We certainly have enough observational evidence to show that Hyder flares can be associated with both CME’s and energetic particle production. For the moment, the question of Hyder flare production mechanism appears unresolved, and will probably be sidelined until the more significant (and undoubtedly related) issue of CME – flare production mechanism is sorted out.

The bottom line is that at this stage in solar physics we do not really know what produces a flare nor what produces a CME. There are competing theories, but all tend to have deficiencies with respect to matching the observational evidence. We certainly believe that they all depend on the reconfiguration of magnetic fields as their primary energy source, but in the final analysis, we really only believe this because we can conceive of no other solar energy source of sufficient magnitude.

O/T but want to post this before going offline, as Prospect is a respected centre left magazine, and this is pretty good:
24 Feb: Roddy Campbell: Too hot to handle
But there are problems, even if you do this carefully. The first is urbanisation. Ideally, thermometers would be in the same place for long periods and unaffected by people. Yet they are often placed near airports, for example, where they are susceptible to an “urban heat island” (UHI) effect, as traffic increases or runways expand…..
The good news is that now, post-climategate, the CRU and the Met Office have released data they had claimed was protected by copyright, or subject to confidentiality agreements. So the scandal has encouraged greater openness. But it has done less to solve a second problem, which arises when you try to deduce temperatures going back thousands of years. Palaeoclimatology (climate study of the history of the Earth) is harder than short term measurements, as there are no records. Temperature changes must be inferred through tree rings or ice cores. Yet some tree cores, for instance, suggest different histories from one side of the tree to the other, while their growth is changed by rainfall and CO2 as well as temperature. Another problem comes with the infamous “hockey stick” graph, devised by US climatologist Michael Mann and featured prominently in Al Gore’s film An Inconvenient Truth. This used tree ring data from Russia and the US to show temperatures gently falling for most of the last 1,000 years, then shooting up from the middle of the 20th century, like the end of a hockey stick. Yet the graph seemed to miss two crucial periods: the “medieval warm period” from the turn of the last millennium to the 15th century, and the “little ice age” at the start of the 17th century, when the Thames regularly froze. Mann claimed these periods were local in nature; sceptics, meanwhile, suspected that the techniques used to create graphs like the hockey stick had been designed to favour the idea that warming in the second half of the 20th century was unprecedented.
There is no conspiracy here. But the scientists involved in climate research for the past 30 years may have enjoyed their golden age too much. Research grants have flowed freely, although not, of course, as freely to scientists with contrary views. I am far from being a climate change denier. It seems perfectly likely that we are having, or will have, an effect on warming through the higher concentrations of greenhouse gases. But the evidence is not yet clear; there were, for example, periods of warming in the 19th century almost identical to the modest warming we seem to have experienced since 1975. We cannot rely on highly imperfect climate models as a basis for policy initiatives that cost billions and change how we live. An accurate and unbiased temperature record is critical.

I enjoyed this one and hope the great filament does something extraordinary where we can observe it. In these wavelengths a great pumpkin does come to mind. The other EIT images, not so much.

Of course the advertisement that appeared just below the article graphic “The Hyder Mechanism” was a video ad for the Blu-Ray DVD of the movie “2012”!
Sweet zombie jesus, maybe this filament will melt the Earth’s crust as Al Gore believes with it being millions of degrees a few miles below the surface of the Earth’s crust… melting now due to modified neutrinos from the filament heating The Core (another fantastic yet unobtainium film). Ok, maybe not… back to reality from the Al Gore 2012 melting crust soothsaying we’re all doomed zone.
This is a really cool filament, unless it bakes us that is. It is there to remind us that the sun Sol is a never changing constant that can’t influence the climate or weather outside of the known measurements – as if the sun Sol obeys our knowledge of it.
Clearly Sol beats to a different drummer with a more complex chaotic dynamic symphony that we likely can even ever full imagine or know.

It sounds like a Hyder flare can (although not usually) be associated with a coronal mass ejection, if I understand this article correctly.

It collapsed around 17:00 UTC yesterday after what have may been interaction with the formation flying at about the 11:30 position just above the sun on this LASCO C2 image taken 17:06 UTC. You can clearly see the flare shooting under it.

The most prominent body in the formation is the one with a small tail under and there are 5 bodies around it of which one is under the flare.

We have had a brief exchange in the past on the Carrington event and on the likelihood of another one happening and the devastation that would wreak on Earth. Frankly I would be far more concerned about such an event that I am about man made climate change.
My question is; does this current flare have any of the same characteristics of the Carrington flare or are they formed in quite different ways and will have quite different effects?

Well it is gone now, but such filaments can persist for months. They are ‘curtains’ of cool dense material hanging in the magnetic field of the Sun. As long as the magnetic field is not disturbed by nearby sunspots, the filament can hang there for weeks or months.

A million degrees – like the earth’s core?
Sorry couldn’t resist the Al Gore ref – as always appreciate the clarifications. While I might have your attention for a sec, I was curious about the alleged (by NOAA’s climate.gov) up to 10% of GW due to solar imcrease. Could you point me to some further, trustworthy and scientifically solid, reading on the subject and/or care to share your thoughts? Also, ever heard that there has been a .1% increase in solar output – is that a real or spurious reference?

Now teasing NASA and SOHO with unpredictable solar filaments.
There are thousands of filaments in every cycle. They are clouds in the solar atmosphere and are not subject to prediction, just like individual clouds in the Earth’s atmosphere are not.
NickB. (01:28:12) :
A million degrees – like the earth’s core?
Yes, actually more like 2 million [just like Gore 🙂 ], but in the solar corona. A little bit of thought can show you that the corona must be very hot. Here goes: The Sun’s gravity [in the atmosphere] is 27 times stronger than the Earth’s, so the solar atmosphere ought to be very compact and only be a thin layer as it is held down by the strong gravity. Now, hot air expands, so if the corona was VERY hot it could expand against solar gravity and form an extended atmosphere around the Sun, as it, in fact, does. QED. The upper corona is so hot that it can even escape from the clutches of solar gravity. This is the ‘solar wind’ sweeping through the solar system.
I was curious about the alleged (by NOAA’s climate.gov) up to 10% of GW due to solar increase. Could you point me to some further, trustworthy and scientifically solid, reading on the subject and/or care to share your thoughts?
I think the saying is that no more than 10% is due to the Sun. A good reference [I know and trust Lean] is http://www.leif.org/EOS/LeanRindCauses.pdf paragraph [17].
Also, ever heard that there has been a .1% increase in solar output – is that a real or spurious reference?
The solar output swings 0.1% from solar minimum to maximum and back.

My first encounter with a filament was a few years after the peak of Sun Spot Cycle (SSC) 22. It was during 1993. One of the local astronomical societies that I belong to here in New Zealand ( The Foxton Beach Astronomical Society) has a late 19th Century 5 inch Cooke refarctor fitted with a Lumicon 0.7 degree bandwidth H-alpha filter. Once your eye settles to the light properly ( a black hood helped with the adjustment, but was a struggle to wear in the summer) an observer could see the background colour change from red through orange and on to yellow. By this stage you could see a lot of detail.
My first view of a filament stopped me in my tracks. Once your eye is properly atuned to the right wavelength then the sun reveals amazing details. With the more fine tuned 0.1 degree filters surface detail is run of the mill stuff these days. Not based upon statistics but my own memory, I found that typical filaments were as common as sun spots. Someone else may have a figure on that.
The quiescnt ones need a lot of patience if one is looking for serious activity. When a hedgerow prominence or when it rolls over onto the surface of the sun and becomes a filament, can have dramatic collapse and release events which then lead to the Hyder Flare. Amazing to watch some of this. I hope some of you get the chance to do the same.
Cheers

p.s. my old solar mentor Merv Loper of the F.B.A.S., alerted me to the problem of the I.P.C.C. back in ’93. He sensed my scepticism of the growing tide of CAGW, even back then! Good onya Merv!

For Peter Whale:
It’s a confused article in so many ways. Maybe the NASA article that they “hang their hat on” isn’t great, I don’t know, but in initially grasping hold of what that specific article did or didn’t say, the “American Thinker” subtly moves the focus to the general climate science theory of how energy moves around in the atmosphere.
If you are only concerned with what the original science educator guide said, you can ignore my post.
If you asked your question because you want to know how valid
the “American Thinker” points are for the general atmospheric theories, then read on..

To make this idea seem plausible, therefore, it’s crucial to fix people’s attention on the 1% of the atmosphere that can be heated by radiant transfer instead of the 99% and more that is heated by direct contact with the earth’s surface and then by convection.

50 years of physicists got it wrong because they missed that point?
My comment isn’t about what anyone believes about how much the planet has heated up because of CO2 or how much it might heat up in the future. That’s all mixed in with the amazing complexity of climate.
No, this is about how to understand the basics of how heat moves up from the surface and out of the atmosphere.
“American Thinker” have done a a conjuring trick.
Implying “only 1% of gases absorb longwave radiation so therefore this effect is only 1% of what happens in the atmosphere
Is it true that physicists have ignored convection (and conduction which hardly rates) and latent heat removal (which the article ignores)? No, they have actually worked out the the energy balance through the atmosphere by considering all of these factors.
The article is so confused that rather than picking apart all of the errors it’s easier to start by understanding the basics – take a look at the series that start with CO2- An Insignificant Trace Gas
If time permits I might do an article about the “American Thinker” article in the next week at Science of Doom.

While filaments might look good in media releases, the true story of SC24 is not in the spotlight. It might be more prudent to ask “what is this cycle doing compared to previous cycles?”
To date the cycle appears to be a loner of sorts, a protracted minimum followed by a big upsurge in one hemisphere. Also we see 2 recurring regions in both hemispheres that have produced solid regions for 3 rotations. This did not occur even at cycle max of SC23.
The northern hemisphere is at present totally dominate, the southern hemisphere although having the same recurring region displays a fraction of the overall activity. Very early days.

February 25, 2010 4:46 am

The sad fact that the enormous magnetic filament on the Sun has for the citizens of planet Earth is just this and nothing less:
1. Research agencies [NAS (National Academy of Sciences), DOE (Department of Energy), NASA, NOAA, etc] that receive our tax funds to stay abreast of knowledge and to protect us from harm have absolutely no idea what the Sun will do next.
Why?
2. NAS (a nongovernmental, private, self-perpetuating, “old-boys club”) reviews the budgets of these research agencies. NAS has used control of the purse to train scientists with grant funds – the same way that Pavlov trained dogs with dog biscuits.
How?
3. To receive grant funds, scientists must think in unison with the opinions of those who control the grant funds.
Consequences?
4. Although life on Earth is totally dependent on the Sun, NAS and its well-trained army of “scientists” [astronomers, astrophysicists, climatologists, cosmologists, nuclear, particle and solar physicists] have manipulated data and deceived the public about the Sun’s size (Earth actually moves through the outer layer of the Sun), its origin, composition and source of energy – misleading us to think that we need only worry about changes in TSI (total solar irradiance)!

Leif, loved the article you linked to. Easy to read and understand. I appreciated the mention of models not adequately accounting for cloud influences. However, my question is that when empirical evidence based models and mathematical calculations of the various influences on temperature trends didn’t match up to the temperature data set and recent global climate models, I wonder if the authors spent any time talking amongst themselves as to whether or not the CRU temperature data set might have some errors in it (since their analysis of influences, both natural and anthropogenic) seems to cover only about 76% of the entire temperature rise). And I wonder if they are talking about that now. The remaining portion of the trend, and 24% is a large chunk, is either a cloud mystery (which is, in my opinion, not showing a great deal of correlation so far based on my review of the literature) or an error in the temperature data set from which the trend is calculated.

If only kinetic energy is involved then, up there in the sun was Hannity throwing his football that produced such a phenomenon!
From two thousand years ago, from the gnostics and the agnostics, two antagonist parties formed: The ones who affirmed that knowledge of the truth, of the fundamental law/laws, was accesible to man and those ones who deny that, who conditioned science, knowledge, to an official Church, to a political bureaucracy as the intermediary between man and knowledge, only accesible through them.
This situation has continued up to the present, with an official and, of course, settled “dogma” (aka “science”) which virulently rejects knowledge as impossible, universal laws as inescrutable, and teach us reality it is rather an inextricable chaos.
That it is and it has always been a lie. There is no and there has not ever been any opposition in nature, any dicotomy. to say it plainly: There is nothing beyond, below, above or under the electromagnetic spectrum, which, of course, it probably extends a little beyond our instruments can now detect.
Then, life, also it is not a phenomenon to be neither separated nor remain unexplained in the one and only field that exists.
Philosophers, like Pitagoras, studied and described reality in quite simple terms and without any ulterior sofistications invented by the official churchs, with instruments as simple as his monochord.

The material is actually falling back on the sun all the time, but is replenished at the same time looking as if it is permanently there. The magnetic field holds the material temporarily during the passage in and out of the filament. If the magnetic structure is disturbed, the filament may erupt and a CME results.

The fact that the satellite temperature anomaly series demonstrates similar influence patterns across latitudes and forcings in terms of the temperature anomaly, I would agree that overall, the various influences analyzed are indeed robust in terms of their degree and action of influence as a function of latitude. No argument there, though I did notice the relatively large discrepancy between GISS and satellite in the NH latitudes, where most of the ground sensors are located.
I picked up on the non-volcanic aerosols comment in that it’s parameters may not be well modeled. Particulate matter comes from several sources, anthropogenic as well as dust storms and salt spray that are tied to ENSO patterns of cold/dry and warm/wet influences. I wonder if the authors thought about differentiating natural versus anthropogenic sources? To what degree does only the anthropogenic portion influence the cooling temperature anomaly?
I also zeroed in on the greenhouse gas piece in that no effort was made (or did I miss it) to determine natural sources of the variance in greenhouse gases from anthropogenic sources. You must admit that ENSO influences greenhouse gas production as a function of growth and decay cycles on seasonal lush plant and animal growth on land and sea or lack of growth on a decadal scale (IE the greening of the planet). To what degree does only the anthropogenic portion of the rise in greenhouse gases influence the upward temperature anomaly?

I’ll take a stab at this. Given that they are attached in the Sun spot area, I would guess that they follow the same butterfly pattern of Sunspot progression from the poles towards the equatorial area as the Sun ramps up and then down. As to which direction they spew and loop forth, I haven’t the foggiest other than to guess that they might loop up and somewhat away from the direction of the Sun’s rotation? And I would guess that this depends on what speed the particular belt the filament is in is rotating at?

The event did not produce a bright solar flare, as sometimes happens when filaments erupt, but there was a coronal mass ejection (CME). SOHO coronagraphs observed at least one and possibly as many as three clouds billowing away from the sun:

El Nino is a major driver of weather pattern variation, in both long and short term ways, so I think ocean influences are adequately covered. However, point taken Ed. I would have liked to see the PDO in the mix since you can various combinations of PDO and El Nino/La Nina/Neutral conditions that have their own temperature derivatives. In addition, if atmospheric oscillations other than trade winds have decadal influences (IE AO), then we need another go at this.
Re: your mention of CO2: The decadal greening of the planet as well as El Nino decadal patterns also have smaller seasonal trends that are loosly tied to each other so it is no surprise that CO2 tends to follow along with ocean cycles.
What fascinates me is the notion, based on models, that more CO2 will re-radiate more long wave radiation as well as cause enhanced water vapor which will add to the greenhouse blanket and bring us nearer to the “tipping point”. This would show up in a diminution of OLR (long wave radiation) being detected at the outer edge of our atmosphere, and an increase in water vapor. That is not the case. Neither show any increasing trend when compared to CO2 increasing trends as measured at Maunu Loa. So far, it appears that whatever affect our greenhouse blanket is having, regardless of its composition, that affect seems to be flat lining in terms of OLR and water vapor.

From the post:
“Of late, the Hyder mechanism has come into question. Some people (notably Zirin) have questioned whether infall occurs, stating that the magnetic reconfiguration must always produce ejection. The respective roles of flares and CME’s in solar active processes has also been hotly debated, and this has implications for the exact mechanism of Hyder flares.”
“The bottom line is that at this stage in solar physics we do not really know what produces a flare nor what produces a CME.”
Evans (22:56:37) commented: “A good example of the science isn’t ‘settled’.”
Dr. Svalgaard (07:04:53) commented: “The usual suspects rear their heads…”
It would seem that my comment is in line with what is stated in the post.
The problem with Dr. Svalgaard is that he apparently feels compelled to disparage most anybody who persists in disagreeing with him.
As if Dr. Svalgaard is an oracle; of course, he is not, he’s a scientist, one of many, and the many have diverse opinions.
But really it’s just a naked display of hostility.
And displays of hostility towards those who disagree are unbecoming of scientists who claim to follow the empirical scientific method.
Disagreement is part of the empirical scientific method. Disagreement is not justification for hostility.

Article’s conclusion:The bottom line is that at this stage in solar physics we do not really know what produces a flare .
The operative word is ‘really’. There are lots of ‘real’ details that we are investigating, but we do know the basic mechanism.
I also asked when filaments are more active.
And I told you that there are 10 times more filaments on the active sun.
I truly do not understand how magnetic fields are not indicative of flows of plasma generating the magnetism. Talking about magnetism as if it occurs de novo simply seems like half an answer.
A flow of plasma does create a magnetic field. A flow of an electrical conductor [a copper wire or a solar plasma] across an existing magnetic field can greatly amplify and re-orient a magnetic field and that is how sunspots are formed.
how the filaments worK? It would be more productive to state your believed mechanism, rather than your condescension.
As I have already explained, filaments condense out of the corona where the magnetic field horizontal and then bends down that field leaving the filament ‘hanging’ in and supported by the field. This is stable configuration if the field does not change too much. Rapid changes of the magnetic field in the surroundings of the filament can upset the balance and cause the filament to collapse or the erupt. Often a new filament forms in the same place and the process repeats.

“The plasma consists of equal number of negative and positive charges so is not an electric current, that is the reason.”
What would make an equal number of negative and positive charges flow in the same direction along a magnetic line of force? That doesn’t make any sense whatsoever. Positive ions should flow in one direction and negative ones should flow in the opposite, either way, they’d both generate a field that would reinforce the other due to the opposing directions.

February 25, 2010 2:34 pm

mikelorrey (14:25:54) :
“The plasma consists of equal number of negative and positive charges so is not an electric current, that is the reason.”
What would make an equal number of negative and positive charges flow in the same direction along a magnetic line of force?

It depends on the ratio between the kinetic energy of the plasma and the energy in the magnetic field. In the Sun and its lower atmosphere, the kinetic energy is much larger than the magnetic energy so the movement of the plasma rather than the magnetic field determines where it goes. Suppose within the plasma you tried to push the electron out ahead of the ions [making them go in opposite directions], then an enormous electric field would build up that would oppose the separation of the two opposite charges [they attract each other], so the net result is that they move together and no current flows.

First, in any well-established scientific field with 1,000s, 10,000s of participants you will always have a few “brave” souls who will have a theory that goes against the vast majority.
Occasionally they overturn or significantly modify the theory. Mostly that’s not the case, even though their ideas usually get published.
Of course any new theory or attempt to overturn an established theory needs to be examined, but it would be wrong to conclude that because someone somewhere published something in a journal that this means the old theory is dead.
Second, many, most probably, “climate scientists” are physicists. The many developments and improvements of the theories of:
– spectral absorption
– atmospheric boundary layer physics
– development and effect of clouds
– aerosols interaction in the atmosphere
All came from physicists.
Third, it’s wonderful to see skeptics. I am one myself. But being skeptical means questioning our own ideas.

Svalgaard (14:14:32) : “[Yes, I was hostile] As it should be. Your pseudo-science must be opposed, not because of disagreements, but because it is dangerous anti-science.”
Dr. Svalgaard, you’re way off base.
I’ve provided peer-reviewed published scientific papers to support my opinions — really, all I’ve been doing is simply reporting the scientists’ assessments as stated in their own papers. Also, I’ve reported well known and accepted scientific principles, i.e., Maxwell’s equations stand for the reciprical physical relationship of electric fields and magnetic fields, as formulated & verified by empirical observation & measurement. Or, when a flow of plasma runs perpendicular through a magnetic field, an electric field and electric currents are generated.
In many cases, the scientists have better qualifications in the subject than you do.
In example, Dr. Anthony L. Peratt, of Los Alamos National Laboratory: Professional biography:
There are other scientists as well, such as Per Carlqvist, Carl-Gunne Fälthammar, and Hannes Alfven, 1970 Nobel Prize winner in physics, and a number of others.
Your beef is with the scientists, themselves, I’m just the messenger conveying their ideas. So, if you are calling anybody anti-science and dangerous, you are calling other scientists anti-science and dangerous.
Is Anthony L. Peratt anti-science and dangerous? Have you contacted Los Alamos National laboratory to convey your concerns about Dr. Peratt?
Time after time, you defend the status quo model or if another scientist challenges the view-point you hold, then that scientist is full of “hype” or worse, like when NASA recently stated in an SDO press release that the long held idea of a “solar constant” was wrong, you called it “hype”. In fact, look up “solar constant” on the internet and you get a whole list of items discussing “solar constant”. Many of your prior comments on this website defend the idea of constant TSI, thus, sunspot activity does not matter.
Dr. Svalgaard, your approach is dogmatic, with mostly the science is “settled” attitude — in fact, you take that position regarding this very post, not withstanding the statements of the scientists, themselves, studying this very issue. I’m sorry, but not exploring the possibilities because one has already settled on a dogma is anti-science and a type of willful ignorance.
Dr. Svalgaard, you are the one guilty of the very thing you accuse me of.
Calling me anti-science when all I’m doing is reporting the peer-reviewed published work of scientists is wrong.

February 25, 2010 4:33 pm

Lief, I am not sure how you wish to categorize me nor why my comments would be threatening enough to the “real science” that I deserved such a demeaning response. However I can see that you have lumped me in with others with whom you disagree. I have read theories that claim a more electric theoretical framework. I don’t buy the whole picture, but some of their interpretations I find interesting and fill certain voids. That Alfven could speculate on the electrical nature suggests that such thinking is not just the domain of a few fringe nuts. Alfven’s model even had the filament positioned as we have now observed so I wondered what other might know about Alfven. Has Alfven fallen from his Nobel heights, and is now deemed to also be a “nut” by modern physicists?
In my reply to you, I repeated the fact that I asked about when filaments are observed, not to say you ignored the question, but to illustrate that I entered the thread seeking more information, not claiming to know anything more. You did indeed answer half of my questions, which I appreciated. I am still curious about correlation with the overall strength of solar magnetic field.
My speculations seem innocent enough if for no other reason than the fact that my elementary understanding of physics treats electromagnetism as one force in which a magnetic field surrounds and arises due to an electric current or is the result of a changing electric field. And mainstream explanations that refer only to magnetism always seem like only half of an explanation. When you say “Rapid changes of the magnetic field in the surroundings of the filament can upset the balance” I simply ask what causes the magnetic fields to change? Changes in plasma flow? Why does the magnetic fields create the filaments where they do?
I hear the ideas of electric fields dismissed, as you have done in a recent reply, based on the notion that in plasmas the negatives and positives will be attracted to each other and neutralize the field. You said “plasma consists of equal number of negative and positive charges so is not an electric current”. I am then confused because such explanations that only use magnetism, seem to remove the electric from “electromagnetic” . Such explanations also imply there can not be separation of charges in space plasmas. But that contradicts my understanding of the Van Allen belts in which it is observed that the outer belt is mostly negative electrons and the inner bet is mostly positive ions. Doesn’t that create an electric field?
I have no problem with being wrong about any of this. Nor do I have a problem that there may be a few lunatics that ask the same questions making strange bedfellows. I am just trying on various concepts to see how they fit. But I am angered to think that I would be attacked as a “nut” for speculating about what has in part, a legitimate basis in the laws of physics and known observations. The intensity of your reaction makes me wonder if there is a culture within mainstream astro/solar physics that has decided to only speak in terms of magnetism as a gate-keeping mechanism to keep out the fringe proponents of a more electric view. Sweeping personal attacks do nothing to help my understanding nor that of others, and certainly doesn’t make this blog look any more scientific.

Jim Steele (16:33:15) :
Jim, you are right to wonder if there is some kind of bias and prejudice against a full electromagnetic view of the Universe in some quarters of the astronomical community.
Because as Dr. Svalgaard makes quite clear there is such a bias.
But they have a three-fold problem: One, magnetic fields are ubiquitous in the Universe at every scale; two, electromagnetism is a fundamental physical force, as expressed in Maxwell’s equations, not just magnetism; and, three, the status quo, in astronomy, denies that electromagnetism plays a fundamental role in the Universe.
So, Dr. Svalgaard and others are in the uncomfortable position of denying that a fundamental force, electromagnetism, plays a fundamental role in the Universe, and it gets more uncomfortable because the fundamental force, Dr. Svalgaard and others subscribe to, gravity, is 39 orders of magnitude weaker than electromagnetism, and in situ observation & measurement and remote full electromagnetic wave spectrum observation & measurement (telescopes, both Earth based on space based) have detected evidence of electromagnetic processes and structures, both in the solar system (aurora) and in distant space large structures (galaxies and star formation).
The scientific evidence is substantial, but it contradicts almost all of their models based solely on the fundamental force of gravity.
That’s why they refuse to discuss anything beyond magnetism — even though it is only half of the fundamental force of electromagnetism.
Yes, in Dr. Svalgaard’s view, it’s dangerous to discuss “electromagnetism”.
Because where would their gravity “only” model be then?

There’s a nice little movie on spaceweather.com, see link below (Thanks, Anthony, this is a nice change of pace!):
“Solar and Heliospheric Observatory (SOHO) images bracket the eruption between 0719 UT and 1919 UT on Feb. 24th. The event did not produce a bright solar flare, as sometimes happens when filaments erupt, but there was a coronal mass ejection (CME). SOHO coronagraphs observed at least one and possibly as many as three clouds billowing away from the sun: movie. If any of this material is heading for Earth–a big unknown!–it would arrive on Feb. 27th or 28th. Arctic sky watchers should be alert for auroras on those dates.”

James F. Evans (17:22:05) :
..force, electromagnetism, plays a fundamental role in the Universe, and it gets more uncomfortable because the fundamental force, Dr. Svalgaard and others subscribe to, gravity, is 39 orders of magnitude weaker than electromagnetism, and in situ observation & measurement and remote full electromagnetic wave spectrum observation & measurement (telescopes, both Earth based on space based) have detected evidence of electromagnetic processes and structures, both in the solar system (aurora) and in distant space large structures (galaxies and star formation).
The scientific evidence is substantial, but it contradicts almost all of their models based solely on the fundamental force of gravity.
That’s why they refuse to discuss anything beyond magnetism — even though it is only half of the fundamental force of electromagnetism.
Yes, in Dr. Svalgaard’s view, it’s dangerous to discuss “electromagnetism”.
Because where would their gravity “only” model be then?
Wish you boys would play nice together.

Another question about filaments. Is the magnetic polarity always the same, say south at the equator and north towards the poles, or does it vary randomly or does the polarity alternate each cycle along with the alternation of sunspot polarity?

February 25, 2010 7:27 pm

And 1 more, do filaments always align as seen here, assuming also a mirror image in the northern hemisphere. Or do they ever align parallel to the equator?

Leif,
Hope you are online.
My lovely wife and I were sitting under a banana tree in the local park in Taipei last night. A beautiful evening and I could even see stars through both the banana leaves and the urban haze/glow. That is rare.
Anyway, I was thinking about distance from earth surface versus value of information on “global” temperatures of earth.
A) I imagined a case where there are (somehow) 3 (or more) spacecraft about 1au (just picked that number to imply distant) from earth. Say these spacecraft are optimally arranged so they continuously measure all spectrum of electromagnetism from the entire earth’s surface simultaneously and continuously over more than 50 years (just to pick a number).
B) Alternately, imagine multiple satellites in orbit (implies relative nearness) doing the same thing.
C) Thirdly, imagine well scientifically designed integrated system of temperature instruments that really does ‘scientifically’ measure all land, sea, ice and atmospheric temps. In other words an optimized temp measurement system, the one you want if money and effort was no object. Say this system has been in place for a period of say 50 yrs or more.
Assume that all of the data from each above is open-sourced to everyone and likewise codes for all analysis of data and openness of method.
Question: Which one has a better capability in theory to measure the global heat content of earth and therefore a meaningful measure of whether the earth is heating or cooling?

February 25, 2010 11:33 pm

Jim Steele (16:33:15) :
However I can see that you have lumped me in with others with whom you disagree.
Jim, I sincerely apologize for lumping you in with the others. That was an unwarranted knee-jerk reaction of mine, for which I’m sorry and for which I hereby apologize.
Has Alfven fallen from his Nobel heights, and is now deemed to also be a “nut” by modern physicists?
No, Hannes Alfven was a god and dear friend of mine and although many of his ideas are no longer supported, his contributions were many and varied and often important. Some of them have been hijacked by the fringe which would make him cringe.
And mainstream explanations that refer only to magnetism always seem like only half of an explanation.
The reason is simple: An electric field depends on the reference frame of the observer while the magnetic field does not. So, the two are not ‘equal’. In a highly conducting plasma, a magnetic field is ‘frozen’ into the plasma and moves with the matter [this was Alfven’s great discovery]. If the conductivity in certain regions of the plasma for various reason drops, the magnetic field is no longer tied to the plasma; this ‘thawing’ of the field under the correct circumstances has important consequences for the interaction of the plasma with bodies embedded in it, as electric fields can briefly occur – Alfven railed against the idea that the field was ‘always’ and permanently ‘frozen’ into the plasma and stressed that the thawing of the magnetic field was at times important – something that people did not always appreciate some 40 years ago. Today we are heeding his words and do things correctly in ways he would certainly approve of.
I simply ask what causes the magnetic fields to change? Changes in plasma flow? Why does the magnetic fields create the filaments where they do?
Since the magnetic field near the surface of the Sun is controlled by the plasma [the magnetic energy is much less than the kinetic energy of the roiling solar plasma] when the plasma moves the magnetic field is dragged along and the magnetic configuration [the field lines show the shape of the field] can change rapidly. And the plasma is in constant motion, mainly because there are large convective motions [like in boiling water]. Imagine a magnetic field line going from one sunspot up into the atmosphere and then curving down into an adjacent spot [this is the typical configuration]. The density in the solar atmosphere decreases rapidly with altitude [just like in the Earth’s atmosphere], so the kinetic energy of the plasma decreases with height much faster than the magnetic energy to the point where eventually the magnetic field becomes the dominant force and guides the plasma flow [you have likely seen images of material flowing along the field lines]. This means that the magnetic field is now containing the plasma and the filament can form in the upper part of the magnetic loops. It also means that on either side of the filament the magnetic field will have opposite polarity [up one leg of the loop and down the other leg], so filaments marks large-scale ‘neutral lines’ between regions of opposite polarity. It is opposite polarities that can reconnect and interact, so filaments are places where explosions can occur, hence the flares.
Such explanations also imply there can not be separation of charges in space plasmas.
This is indeed correct, but with one important caveat: namely that the particles be allowed to stream freely [see below].
But that contradicts my understanding of the Van Allen belts in which it is observed that the outer belt is mostly negative electrons and the inner belt is mostly positive ions. Doesn’t that create an electric field?
The charged particles in the belt are trapped by the strong magnetic field of the Earth and are constrained to spiral along the field lines, bouncing from pole to pole, so are not moving freely and can therefore not neutralize. So you get an electric field from the charge separation, but this field does not control the movement of the particles – the magnetic field does.
I again apologize for the reaction
makes me wonder if there is a culture within mainstream astro/solar physics that has decided to only speak in terms of magnetism as a gate-keeping mechanism to keep out the fringe proponents of a more electric view.
There are no conspiracies here. It is Mother Nature that uses magnetism as the gatekeeper. All serious physicists are in agreement on this [there are always a few that have fallen off the cliff]. The Electric/Plasma Universe folks seem to be driven by underlying agendas of various kinds – religious, political, new-age, etc or simply by the urge to seek explanations that are easy and visual and does not require mathematics or any deeper knowledge [which is hard work to acquire]. These will of necessity be superficial and not represent real knowledge. This dumbing-down of the populace is dangerous to a society that ultimate must rely on since for survival, as we have exhausted the easy picking of the low-hanging fruit. A god example is the very next comment(s), where real knowledge is called ‘dogma’:
Suranda (16:37:34) :
Dogma is dangerously seductive. And anti-science.
James Evans statement above sounds like the voice of integrity. It should be addressed by you scientific dudes, I think.

Jim Steele (19:25:25) :
Another question about filaments. Is the magnetic polarity always the same, say south at the equator and north towards the poles, or does it vary randomly or does the polarity alternate each cycle along with the alternation of sunspot polarity?
Sunspots follow a set of polarity rules as you state [changing with the cycle, etc]. Filaments [as explained above] lie between regions of opposite magnetic polarities, so follow along with the changes of the spots.
Jim Steele (19:27:57) :
And 1 more, do filaments always align as seen here, assuming also a mirror image in the northern hemisphere. Or do they ever align parallel to the equator?
They can have any orientation, although at low latitudes the often go North-South. There is a special class of filaments called the ‘polar crown’ that encircle the North and South poles, along the boundaries of the polar coronal holes. Magnetic fields from decaying sunspots are swept [remember: the plasma moves the field around] by a meridional circulation [the Earth also has that] from lower latitudes towards the poles and a rather strong magnetic field then tends to build up there. This polar magnetic field eventually becomes the seed of the next sunspot cycle.

I think the specific configuration of the sensors doesn’t matter much. There are many ways a good system can be configured [BTW in my previous comment I mistyped good as ‘god’ – so beware of that. In my native language ‘good’ is in fact ‘god’].
One proposal I personally like is a system where satellites [e.g. at the L1 or L2 points] simultaneously ‘stare’ at 1) the Sun 2) the Earth and 3) some stars.

It took me a moment, I had to look up Lagrange points L1 & L2.
So, I think you are suggesting that from the L1 & L2 at the same time,
a) measure the energy from the sun going to L1 and on the same satellite measure the energy from the daytime earth coming to L1
b) measure energy at L2 from the nightside of earth and on the same satellite measure the starlight
Correct?
Q1- why measure the starlight?
Q2 – You don’t see any advantage to spacecraft being more distant than L1 & L2? I personally cannot but just curious.
John

February 26, 2010 1:06 am

John Whitman (00:17:13) :
Correct?
Essentially, yes.
Q1- why measure the starlight?
There are stars that are VERY stable and whose output is VERY constant [over human lifetimes], so yo can check the calibration and produce a record that people hundreds of years hence than verify, since they can measure the SAME star.
Q2 – You don’t see any advantage to spacecraft being more distant than L1 & L2? I personally cannot but just curious.
The problem is to keep the satellite where it is. We want the satellite to stay put as much as possible. That can be done with a minimum of fuel if you place it at L1 and L2.

Thought this might be interesting. Here is the original 1965 Charles L. Hyder scientific paper: Winking Filaments and Prominence and Coronal Magnetic fields:
And another peer-reviewed, published scientific paper:
Title: The field and plasma configuration of a filament overlying a solar bipolar magnetic region
Authors: Low, B. C.
Journal: Astrophysical Journal, (1981):
Partial Abstract: “This paper presents an analytic model for a finite-size straight filament suspended horizontally in a steady state over a bipolar magnetic region. The equations of the magnetic equilibrium are integrated exactly. The solution obtained illustrates the roles played by the electric current, magnetic field, pressure, and plasma weight in the balance of force everywhere in space… The filament temperature can take values ranging from a small fraction to a few times the coronal temperature, depending on the internal electric current of the filament.”
Jim Steele, I hope you find these two papers interesting and enlightening. As the reader can tell, the description of the filament in the second paper is the same as in the instant post. The author clearly identifies the filament as being an “electric current”.

This is a typical example of the twisting of science to conform to wrong physics. Such twisting occurs can occur when the physics is not understood. Nowhere does the author identify the filament as being an electric current. [one might ask for page and line number for such identification]. What does happen is that when external forces deform a magnetic field and the weight of the filament [caused by gravity] does just that, small electric currents are induced. This happens everywhere where there is a dB/dt [that is: a change of the magnetic field]. The fundamental issue is that electric fields are generated by plasma [a conductor] moving in a magnetic field. The electric currents are precisely the neutralization of this electric field preventing the electric fields building up.

Happy to comply with the request:
From the paper, abstract, first page, page 538 of journal, starting at line 6 of the Abstract going on to line 7 and 8:
“The filament temperature can take values ranging from a small fraction to a few times the coronal temperature, depending on the internal electric current of the filament.”
And Section V. Discussion, ninth page, page 546 of journal, line 1 and 2 of Discussion:
“The physical state of the filament plasma and its associated internal electric current system required for force balance are determined by the specific heating and cooling processes taking place in the filament.”
Dr. Svalggard, what part of “…depending on the internal electric current of the filament…” do you dispute?
And, Dr. Svalgaard, what part of “The physical state of the filament plasma and its associated internal electric current system…” do you dispute?
And, of course, the filament’s electric current is discussed in the body of the paper with plenty of supporting mathematical equations.
Taking a step back and reviewing Dr. Svalgaard’s response: Notice Dr. Svalgaard never responds to the specifics in the paper or discusses the specifics of the paper.
Dr. Svalgaard, what specifics in the paper lead you to conclude I have misinterpreted the above two quotes and, indeed, the body of the paper which stands for the proposition that the filaments discussed consist of plasma flowing in an electric current?
The quotes from the paper speak for themselves and Dr. Svalgaard’s response, also speaks for itself, but in a much less flattering way.

February 26, 2010 9:43 am

HI Leif, Your apology is greatly appreciated. Thank you. Likewise your in depth answers are greatly appreciated and informative. Indeed your answers have this a more scientific blog.
But it does generate a few questions if you have the time. The concept of “frozen plasma” makes sense to me only when I think in terms of the Van Allen belts and the earth/solar magnetic fields trapping the plasma. It is easier for me to conceive of this with more solid bodies helping to “freeze” and maintain the magnetic fields for extended periods. It becomes more difficult to understand in the roiling plasma of the sun.
So when you say “Magnetic fields from decaying sunspots are swept [remember: the plasma moves the field around] by a meridional circulation [the Earth also has that] from lower latitudes towards the poles and a rather strong magnetic field then tends to build up there. This polar magnetic field eventually becomes the seed of the next sunspot cycle.” I have difficulty picturing that and have more questions.
Your sunspot answer implies this “seed” magnetic field is “almost perpetually?” frozen in place and recycled. I have also read this I think from a David Hathaway explanation. The biggest question is what is the evidence to suggest a new sunspot has arisen from an old spot? I can’t imagine how that could be proven, so I suspect that notion is more of a logical extension of a model. Additionally then why do seeds change polarity? Where do they go during minimums, has the meridional circulation(solar conveyor belt?) slowed? Why doesn’t the roiling plasma disrupt the magnetic seed. I would assume there are tremendous instabilities much more than those experienced when trying to use magnetic fields to control sustainable nuclear fusion.

James F. Evans (09:26:58) :

A dog has a flea on it and is thus identified as a flea according to your ‘logic’. The associated electric currents are the currents generated by changes in the magnetic field brought about by gravity pulling down on the filament and deforming the magnetic field supporting it. This does not mean that the filament is generated by an electric current. It would be refreshing if you would learn a bit about these things. You are given plenty of opportunity, and I’m always willing to assist.

Jim Steele (09:43:57) :

‘Freezing’ is perhaps not a good word for this, but our language lacks words for things we do not experience; we do not live in a plasma, so have no word for this. What happens is that a changing magnetic field generates an electric field. In a highly conducting plasma, the electric field is shorted out immediately and there can thus not be a sustained electric field, thus no change in the magnetic field. In our daily life we never come across such phenomena and thus have no intuitive understanding of them. A little anecdote might illustrate that we can actually in rare cases observe this directly. I was once standing next to a cyclotron that used powerfull magnets to bend the trajectories of ions. Because of the magnets, no iron tools were used near the cyclotron. There was a bucket for the use of the janitor to clean up spills. The bucket was made of copper. By accident I caused the bucket to tip over. In ordinary life, it would take it but a fraction of a second to fall, but because copper is such a good electrical conductor and because the bucket was immersed in a strong magnetic field, the field was ‘frozen’ to the bucket and the bucket couldn’t fall but had to stay in its position. Copper, however, does have a finite resistivity and the freezing was not perfect, so the bucket did fall, but it took about five seconds to do it [as eddy currents in the copper slowly dissipated]. In cosmic plasmas the conductivity is much higher and the linear dimensions much larger [it turns out that is important too], so the freezing in much more effective.
The biggest question is what is the evidence to suggest a new sunspot has arisen from an old spot? I can’t imagine how that could be proven, so I suspect that notion is more of a logical extension of a model.
It is, of course, not the case that a specific new spot has arisen from a specific old spot. Raindrops are recycled water from previous raindrops, but that does not mean that a specific raindrop that falls on your head now has arisen from a specific drop that fell into a river, was carried into the ocean, evaporated, went into a cloud, and reformed to fall on your head. Same thing with the magnetic fields from old sunspots. A piece of the field is frozen into a blob of plasma and dragged over the solar surface. The plasma partakes in a circulation that carries it into the Sun near the poles and in there circulates to lower latitudes. Since magnetic fields have no ends, some segment of the field lines are outside the blob and are not dragged along with the blob [or dragged with a different speed or direction] and then become stretched and would around by solar rotation. Imagine it is wound around ten times then through a given area perpendicular to the field line, where there before were only one line, there are now ten, so ten times a many field lines results from the winding. Now, the magnetic field strength is simply the number of field lines per unit area, so the field is now ten times stronger. [some people don’t like the image of ‘field lines’, although it is very appropriate in this situation; they prefer to think of just the field strength being amplified as described by a mathematical equation – either way, the result is the same].
All this winding takes place inside the Sun where we cannot see it directly. But just as we can use waves from earthquakes [or man-made explosions] to image the interior of the Earth [and prospect for oil], we can also ‘see’ the distortions of the solar interior braought about by the wound-up field by observing sunquakes. We can, in fact, see ‘through’ the Sun and watch sunspots forming on the backside of the Sun.
A magnetic field exerts a pressure of its own [try to press two magnets together same polarity to same polarity] and so a wound-up strong field has an appreciable pressure of its own. A parcel of plasma surrounded by other plasma must be in pressure balance with its surroundings. If some of that pressure comes from the magnetic field that doesn’t weigh anything, the parcel must contain less material and is thus lighter than the surrounding parcels [with no magnetic field]. This like releasing a piece of wood in water from a depth of, say, a yard: the wood will rise to the surface. Likewise, the magnetic field and when it does a sunspot can form from it. So, as from one raindrop to another later on, it is from one magnetic field to another later on.
That the polarity changes is a bit harder to understand [but only a bit]. Sunspots occur in pairs [simplification, but close enough] with each spot of a different polarity. Observationally [and theoretically as well] we found that the line or axis connecting the two spots is tilted slightly so that one spot [we call that the ‘following’ spot] is at a higher latitude than the other spot. Imagine the fraying spots spreading the fields out over an area around the spots then there is a bigger chance that more of the field that is already at a higher latitude will survive the journey to the pole [it has a shorter way to go] and thus the poles will tend to accumulate preferentially the fields from the ‘following spots’. Now, drag that field inside the Sun, wind it up, and let it [like the wood] resurface years later. If you make a little drawing and keep track off the direction of the field lines, you’ll find that the direction reverses in this process [seen from the outside], so the new spots will have opposite polarities from the old spots.
Why doesn’t the roiling plasma disrupt the magnetic seed.
Because the magnetic field has a linear extension many times larger than that of the ‘roiling’. When you throw a pebble in the ocean you create small circular waves spreading out from where the stone hits the water. These little ripples do not disrupt the monster ocean waves that surfers ride.

Dr. Svalgaard, if the “internal electric current” is not flowing along the length of the plasma filament from one foot to the other foot, where does the electric current flow to and from?
Dr. Svalgaard, your statement is not what the paper says. Please provide the specifics from the paper that supports your assertion.
Dr. Svalgaad, you didn’t answer this question: “what part of ‘…depending on the internal electric current of the filament…’ do you dispute?”
Evans (01:33:47) asked: “Dr. Svalgaard, what specifics in the paper lead you to conclude I have misinterpreted the above two quotes and, indeed, the body of the paper which stands for the proposition that the filaments discussed consist of plasma flowing in an electric current?”
Evans (01:33:47) previously commented: “Notice Dr. Svalgaard never responds to the specifics in the paper or discusses the specifics of the paper.”
Dr. Svalgaard continues this pattern of refusing to refer to the specifics of the paper.
Dr. Svalgaard if you can’t refer to specifics from the peer-reviewed paper (Did you read the paper?) I provided, after you were requested to do so (and, you claim to be the expert) and avoid explaining how an “internal electric current” of the filament is actually an “associated [external] electric current”.
Dr. Svalgaard, your analogy is wrong.
Dr. Svalgaard (10:09:56): “A dog has a flea on it and is thus identified as a flea according to your ‘logic’.”
An “internal electric current” is not analogous to a “flea” on the outside of a dog. Rather, it is an internal constituent of the plasma filament.
The plasma flows in the filament due to the “internal electric current”.
What readers get is a non-responsive word game from Dr. Svalgaard.

James F. Evans (12:42:12) :
if the “internal electric current” is not flowing along the length of the plasma filament from one foot to the other foot, where does the electric current flow to and from?
This is the kind of question that stems from you not understanding the paper or the physics. The filament hangs in a magnetic ‘arcade’ which exists before and after the filament. The magnetic field [as the paper says] may be thought to be produced by a line current [“in the negative x-direction”] located at some distance below the surface. This is just a convenient way of describing the magnetic potential by ‘an equivalent current’ [just like the HCS] . Now, gravity is pressing the filament down across the horizontal field lines. That generates a current in the opposite direction [as the paper clearly describes “in the positive x-direction”]. This current induces “an image current” below the corona, and the resulting configuration is derived from the sum of all the Lorentz forces resulting from these currents. So, again, the currents are not generating the filament, but gravity pressing down on the filament is generating the currents. The arcade is there with or without the filament and does not owe its existence to the filament. So, your statement ‘The plasma flows in the filament is due to the ‘internal electric current” is backwards, as usual.
If you don’t like my analog with the flea, think of the bacteria in your stomach and its output channel forming an internal constituent of you, without which you couldn’t live.

Thank you Dr Svalgaard for your patience and attention here. There seems to be a humongous amount of transmission errors of late, yes? So many orbs, spheres, planet-sized objects around the failing Sun (I think we are still in a profound minimum) and although I’m a huge ET/UFO thinking person, I don’t think these are spaceships.
Something about the holographic nature of the universe ~ of the Sun. I think the physical aspect of our world is declining and the world upon which this one was superimposed is actually coming to the forefront.
Surely you don’t buy the compression artifact scenario, dear Sir? Artifact, yes. Compression, maybe. But the real holographic nature of this physical reality ~ it’s something our world of science has not ventured into. Yet. It’s time.

February 26, 2010 4:57 pm

Jim Steele:
Dr. Svalgaard is wrong.
Filaments are an expression of electric current just as the paper stated: “…depending on the internal electric current of the filament.”
It is important to understand that filaments and prominences are the same.
Once one understands that filaments and prominences are the same structure it becomes clear that, indeed, filaments are plasma flows possessed of electric currents:
From NASA:
“Filaments are formed in magnetic loops that hold relatively cool, dense gas suspended above the surface of the Sun,” explains David Hathaway, a solar physicist at the NASA Marshall Space Flight Center. “When you look down on top of them they appear dark because the gas inside is cool compared to the hot photosphere below. But when we see a filament in profile against the dark sky it looks like a giant glowing loop — these are called prominences and they can be spectacular.”
http://spaceweather.com/glossary/filaments.html
Why?
Because Coronal Mass Ejections (CME’s) are often observed developing from prominences (filaments):
Per Wikipedia:
“A typical CME has a three part structure consisting of a cavity of low electron density, a dense core (the prominence, which appears as a bright region on coronagraph images) embedded in this cavity, and a bright leading edge. It should be noted, however, that many CMEs are missing one of these elements, or even all three.”
http://en.wikipedia.org/wiki/Coronal_mass_ejection
Per Carlqvist and Hannes Alfven address the issue in a peer-reviewed published paper:
Title: Energy source of the solar wind (1980)
Journal: Astrophysics and Space Science
Partial Abstract: “A direct transfer of energy from photospheric activity to the solar wind by means of electric currents is discussed. Currents are assumed to flow in quiescent prominences [filaments, as discussed in the instant post] which occasionally erupt and give rise to expanding loop-like structures in the corona…[CME’s]”
Futher:
“1. Electric Current Models of Cosmic Plasma Phenomenon”
“A model of magnetized plasma can be based either on a magnetic field description or on an electric field description.”
[As expressed by Maxwell’s equations where electric fields and magnetic fields have a reciprical physical relationship. Dr. Svalgaard chooses to only use the magnetic field description and exclude the electric field description. Hannes Alfven acknowledges that both descriptions are valid.]
“The study of these alternative approaches (Alfven, 1968, 1979a) shows that the current description is necessary for the understanding of the formation of double layers, explosive phenomenon, and transfer of energy from one region to another.”
[Dr. Svalgaard rejects using the electric current model for understanding energy transfer from one region to another]
[Double layers in plasma as Hannes Alfven stated are necessary to understand many plasma phenomenon:]
http://en.wikipedia.org/wiki/Double_layer_(plasma)
Continuing with the Carlqvist & Alfven paper:
“We base our model on the current model of solar prominences and solar flares. If photospheric motion in the presence of magnetic fields produces a voltage differences between two points of intersection of a magnetic field line with the photosphere, a current starts to flow along this line. Due to drift motions caused by crossed electric and magnetic fields, matter from the corona is sucked in by this current so that a prominence [filament] is formed.”
So, Alfven and Carlqvist are clear, filaments are flowing plasma consisting of electric current.
Let’s cite two scientific papers that are more recent:
Title: Generation of large scale electric fields in coronal flare circuits
Submission August 6, 2009
“A large number of energetic electrons are generated during solar flares. They carry a substantial part of the flare released energy but how these electrons are created is not fully understood yet. This paper suggests that plasma motion in an active region in the photosphere is the source of large electric currents. These currents can be described by macroscopic circuits. Under special circumstances currents can establish in the corona along magnetic field lines. The energy released by these currents when moderate assumptions for the local conditions are made, is found be comparable to the flare energy.”
http://arxiv.org/abs/0908.0813
To highlight:
“This paper suggests that plasma motion in an active region in the photosphere is the source of large electric currents.”
And further:
Title: Driving Currents for Flux Rope Coronal Mass Ejections
Submitted on 23 Oct 2008
“We present a method for measuring electrical currents enclosed by flux rope structures that are ejected within solar coronal mass ejections (CMEs). Such currents are responsible for providing the Lorentz self-force that propels CMEs. Our estimates for the driving current are based on measurements of the propelling force obtained using data from the LASCO coronagraphs aboard the SOHO satellite. We find that upper limits on the currents enclosed by CMEs are typically around $10^{10}$ Amperes. We estimate that the magnetic flux enclosed by the CMEs in the LASCO field of view is a few $\times 10^{21}$ Mx.”
http://arxiv.org/abs/0810.4210
To highlight:
“We present a method for measuring electrical currents enclosed by flux rope structures that are ejected within solar coronal mass ejections (CMEs).”
Remember, Coronal Mass Ejections, are a “stretched out” filament or prominence that eventually explodes.
When one considers Dr. Svalgaard’s earlier comments where he expressed the sentiment that anybody who presents Alfven’s ideas is anti-science and dangerous, one understands why Dr. Svalgaard persists in denial about the role of electric currents, and that quiescent prominences or filaments are flowing plasma animated by electric currents as stated by Alfven & Carlqvist.
It’s a shame that Dr. Svalgaard’s judgment is clouded by such animosity.

Leif, you in?
Sure, the fact that currents and magnetic fields are mentioned in the same papers is irrelevant to the issue. The way Nature works is quite simple [although the details are messy]: gravity or temperature gradients cause plasma with equal number of positive and negative charges to move around. Magnetic fields are everywhere, and when the plasma is forced by gravity or temperature across magnetic field lines, electric fields are generated. If enough free charges are present, electric currents will flow that will neutralize the electric fields [‘the battery going flat’], unless the plasma movements continue to generate the emf. All energetic effects are caused by the thus generated currents.This is well-known and accepted by everybody who knows event the least of physics.
What Evans is advocating is quite different, namely that gigantic electric currents criss-cross the Universe [without specifying where they come from] generating magnetic effects, solar energy even, flares, you name it. This view, the Electric/Plasma Universe is simply wrong and pure nonsense. They often claim that 99.999…% [with an unspecified number of 9s] of the Universe is a plasma. Even that is wrong, the percentage is in single digits. There was even a time [for about a million years after 380,000 years ago] when the temperature of the Universe dropped below 2967K when there was no plasma at all anywhere in the Universe. Etc, etc, etc. The whole thing is pseudo- and anti-science almost as sublime as Oliver’s. and as I said, a blot on our proudest achievement. It is tiresome to have to point that out again and again, so perhaps it is time simply to let it fall under its own weight. The sad thing is that it probably won’t, as the public will rather drink the Koolaid than think for themselves.

February 26, 2010 9:08 pm

Carla (18:43:30) :
Evans even understands so little that he cites a paper that states: “This paper suggests that plasma motion in an active region in the photosphere is the source of large electric currents”. Just as I said. What he is missing, but the paper, of course, is not, is that those motions must be across magnetic field lines for currents to be generated as I have tried to explain to him so many times. Just waving a piece of copper wire [or any other conductor, e.g. a plasma] in the air imagining for a second that the Earth didn’t have a magnetic field] does not generate electric currents.
Suranda (14:31:24) :
There seems to be a humongous amount of transmission errors of late, yes?
The spacecraft is nearing the end of its life [has long ago exceeded its ‘nominal’ life span], so these failures will become more and more frequent, until one day the systems will go completely dead.
Just The Facts (18:21:44) :
http://news.bbc.co.uk/2/hi/3869753.stm

It and the other paper are based on finding by Lockwood et al. extending a study of me long ago [see: http://www.leif.org/research/GC31B-0351-F2007.pdf ], that the sun’s magnetic field has more than doubled in the last 100 years. Recent results, both by Lockwood and by me [and others] have shown that this conclusion is in error. The calibration of the cosmic ray data that was based on that erroneous conclusion is therefore not valid, and there is today very little support for the notion that we are [or have been] at a 1000 year or 10,000 year [or whatever large number people quotes] high in solar activity.

The data does not support it:
1) cosmic ray intensity has been flat since 1950s [apart from the 11-yr period that hardly shows up in temperatures]
2) Examining the largest Forbush Decreases shows no effect
3) the effect is supposed to work though the albedo, but the latter does not show any marked solar cycle effect.
Again, it is possible that there is a very small effect that we have not been able to detect yet, so the mechanism may be viable although its amplitude may be small.

The variation is very small and has thus a very small effect. If the ‘increase’ in temperature since 1965 is mainly due to artificial adjustments rather than being real [see: http://wattsupwiththat.com/2010/02/26/a-new-paper-comparing-ncdc-rural-and-urban-us-surface-temperature-data/ ] then there is even less evidence that the high solar activity during that time had any climate effects.
What do you think of the possibility that variations in solar activity impact Earth’s climate system through mechanisms that we have yet to discover?
Before we introduce [or believe in] mechanisms not yet discovered we should be relatively certain there is something to be explained, and as I just pointed out, any solar effects seem very elusive. But I guess that one might maintain that impacts not yet discovered could be explained by mechanisms also not yet discovered.

Anti-science is not a valid ‘opposing view’. Dissent is critical to good science, but the dissent has to be scientifically valid.

Carla (18:43:30) :
Thank you very much for providing the full peer-reviewed paper:
Title: Generation of Large Scale Electric Fields in Coronal Flare Circuits
Authors: H. One and G. J. Mann, Astrophysical Institute Potsdam
Published: Cen. Eur. Astrophys. Bull. (2009)
http://arxiv.org/PS_cache/arxiv/pdf/0908/0908.0813v1.pdf
It is informative and interesting reading.
Anybody who wants to have a better understanding of the physical explanation of CME’s (and filaments) is well advised to read and study this paper.
Dr. Svalgaard (20:48:31) stated: “What Evans is advocating is quite different, namely that gigantic electric currents criss-cross the Universe [without specifying where they come from] generating magnetic effects, solar energy even, flares, you name it. This view, the Electric/Plasma Universe is simply wrong and pure nonsense. They often claim that 99.999…% [with an unspecified number of 9s] of the Universe is a plasma. Even that is wrong, the percentage is in single digits.”
Carla, notice Dr. Svalgaard skips over without comment the fact that he was previously asserting that the filaments did not have an “internal electric current” or that the filament did not express an electric current.
But the Carlqvist & Alfven paper and the full paper you, Carla, provided make quite clear that in fact filaments are an expression of flowing plasma that constitutes electrical current.
Carla, one has to ask, themself, why Dr. Svalgaard was so determined to obscure this fact that he was willing to mislead readers. And, if so, how much credibility should readers give Dr. Svalgaard on this subject or even on other subjects?
Carla, I’m presenting the considered assessment of recognized scientists:
Hannes Alfven, 1970 Nobel Prize winner in physics
Anthony L. Peratt, Los Alamos National Laboratory
Carl-Gunne Fälthammar (list of papers):
http://www.ee.kth.se/php/modules/people/publications/437.pdf
Per Carlqvist
And many other reputable scientists.
Yet, Dr. Svalgaard attempts to label me and others, here on this website, who convey the ideas of these scientists by presenting peer-reviewed scientific papers and recognized physical principles, “anti-science”, “dangerous”, and “nuts”. This reveals how manic Dr. Svalgaard is about this issue and, I’ll note, many of his associates are equally manic & hostile.
And, it does rightly cause reasonable people to question Dr. Svalgaard’s ability to be objective and honest in his discussions when these issues are involved.
(As this discussion has demonstarated what Dr. Svalgaard is capable of when he thinks it’s “necessary” to protect his world-view.)
Of course, when I pointed out that I’m simply conveying the ideas of reputable scientists and that when he labels me “anti-science”, “dangerous”, and “nuts”, he is really calling his fellow scientists all these names — Dr. Svalgaard backed-off.
In reviewing the peer-reviewed published paper by One and Mann, one can see a line of papers that support the idea that electrical currents and electric fields are important in astrophysical relationships.
The insight that Alfven provided is that these electromagnetic phenomenon are scale independent, therefore, can be studied in the plasma laboratory and, now, in situ satellite probes, and, thus, these principles can be applied to distant astronomical structures & processes because of the scale-independence of electromagnetism, a fundamental force of Nature.
Carla, notice how Dr. Svalgaard has conflated “Electric/Plasma Universe” together? This is part of his “slick & shtick” routine that he often employs.
The Plasma Universe concept is seperate and distinct from ‘Electric Universe’, which is a more expansive extension of Plasma Universe concepts, but implacable critics, such as Dr. Svalgaard, often conflate the two for maximum prejudical effect.
Dr. Svalgaard: “They often claim that 99.999…% [with an unspecified number of 9s] of the Universe is a plasma. Even that is wrong, the percentage is in single digits.”
The percentage of plasma in the Universe is only in “single digits” if your gospel & faith is placed in the existence of so-called “dark” matter and “dark” energy, which have never been directly observed & measured and its advocates can’t even describe or explain its physical nature.
The observable Universe is, indeed, 99.99% plasma, and even the good doctor knows not to deny that:
The following link lays out in its footnotes (20 footnotes) citational support for the assertion that over 99% of the observable Universe is plasma:
http://www.plasma-universe.com/99.999%25_plasma
Of course, this is why Dr. Svalgaard is willing to “go to the wall” to assert the existence of so-called “dark” matter, because without it, his whole world-view crumbles into the ash-heap of history.
And, indeed, I suggest this fear of his world-view crumbling to dust likely motivates Dr. Svalgaard and his associates to act in this overall ruthless fashion and engage in what I call his “slick & shtick” campaign.
Dr. Svalgaard: “…the public will rather drink the Koolaid than think for themselves.”
Actually, Dr. Svalgaard is the one who attempts to indoctrinate as much as he can and intimidate & mislead as much as he thinks necessary to acheive his objectives — it’s clear, for Dr. Svalgaard, the “ends justify the means”.
However, the “ends justify the means” strategy & tactics is completely antithetical to the Empirical Scientific Method.
Dr. Svalgaard (21:08:10): “What he [Evans] is missing, but the paper, of course, is not, is that those motions must be across magnetic field lines for currents to be generated as I have tried to explain to him so many times.”
False.
I recognize the necessity of magnetic fields and their indespensible role. How may times have I cited Maxwell’s equations which speak to this requirement.
The difference between me and Dr. Svalgaard is that he holds up the magnetic field analysis as the only scientifically valid analytical tool, purposely excluding an electric field analysis, while I stand with Hannes Alfven and note that both electric field and magnetic field analysis is valid, and, also, I stand with Alfven to state the electric current analysis is necessary to properly understand formation of double layers, explosive phenomenon, and transfer of energy from one region to another.
Alexander Feht (23:24:38) wrote: “Dr. Svalgaard doesn’t see any significant correlation between solar activity and Earth’s temperature.”
And Feht continued: “Right. After this stunning revelation, why would anybody pay attention to whatever Dr. Svalgaard has to say?”
To which Just The Facts (23:45:20) responded: “I think it’s probably because Leif is one of the foremost solar scientists in the world.”
Just the Facts, how do you know that?
I’ve looked for Dr. Svalgaard’s curriculum vitae and can’t find it — yes, a list of papers (it’s not clear how many were ever peer-reviewed or published), but certainly not a biography of educational attainments or what institutions Dr. Svalgaard worked at or researched at.
What little I have found on the internet suggests that he taught at Stanford University over 30 years ago, but primarily has been a computer programmer (a very good computer programmer) that has worked for various companies and, now, owns his own company in parnership.
So, Dr. Svalgaard’s time has been divided and it’s unclear how much influence, prestige, high regard, or scientific value Dr. Svalgaard’s work has been given in the field of helio-astrophysics.

Leif Svalgaard (08:10:20) quotes Just The Facts (23:35:06)
“I struggle with the possibility that variations in the local G-type main sequence star do not have significant impacts on Earth’s climate system.”
Leif replies: “The variation is very small and has thus a very small effect.”

Leif, you do not understand the Sun, nor its influence on planet Earth, because you have steadfastly refused to consider these experimental data:
a) Neutron repulsion is clearly shown in nuclear rest mass data for all nuclei with two or more neutrons.
http://www.omatumr.com/abstracts2003/jfe-neutronrep.pdf
b) The results of literally hundreds of different analysis of elements and isotopes in meteorites and planets are explained if the Sun itself exploded five Gyr ago to produce the solar system in this manner:
http://www.omatumr.com/Origin.htm
c) The top of the solar atmosphere is 91% Hydrogen (H) and 9% Helium (He) because H is the lightest element (element #1) and He is the next lightest one (element #2). Solar mass fractionation is experimentally observed across isotopes (3 to 136 atomic mass units) in the solar wind and across s-products (25 to 207 amu) in the photosphere [“Solar abundance of elements from neutron-capture cross sections”, The 36th Lunar and Planetary Science Conference (LPSC), Houston, Texas, March 14-18, 2005].

You are entitled to think whatever you want. You thinking it, however, doesn’t make it a fact.
One of the foremost solar scientists in the world says that there is no significant correlation between solar activity and Earth’s temperature. Therefore, it must be so.
I am going to sleep naked in the snow from now on: what do I care about solar activity or lack of it? The foremost scientist in the world told us it doesn’t matter.

Hey hey we know how you feel. After Al Gore koolaid withdrawls about CO2 I too thought the sun as the primary climate change factor. Not long on that path when I start seeing Dr. S. repeatedly state not a primary. huh and THEMIS confirmed what we already knew. huh again.
Now I pay attention to the Local Interstellar environment. Could it be so simple as to say denser extraterrestrial clouds make denser terrestrial clouds, who knows?

As much as I hate appealing to authority [like to Alfven, Birkeland, Peralt, etc], a good measure of someone’s standing in a scientific community is the number of keynote and invited talks he/she is giving at scientific meetings and conferences. Here is a small selection of recent ones given by me:

Dr. Svalgaard:
I’m happy to see you’re on a speakers list for a seminar, but I’m not sure that’s evidence you’re “one of the foremost solar scientists in the world.”
As far as the rest, I don’t consider it a personal attack to note there’s a lack of information to make an assessment about somebody’s professional qualifications (why don’t you just supply the readers that information instead of complaining about it).
And, Dr. Svalgaard, considering you were the first to offer up personal attacks on this thread by calling myself and others, “anti-science”, “dangerous”, and “nuts”, your complaint about personal attacks rings hollow.
What it sounds like to me is a ploy to generate sympathy and provide an excuse for why your’re failing to respond to the substantive arguments I made in my last comment.
In other words, it’s a diversion — but not effective.
What about those substantive arguments I raised about the physics? Care to respond to those arguments, Dr. Svalgaard?
Dr. Svalgaard, are you still calling Dr. Anthony L. Peratt of Los Alamos National Laboratory “anti-science”, “dangerous”, and “nuts”?

concur here too.
That brings me back to solar activity. Looking further back, do you see any correlation between solar activity and the Sporer, Maunder, and Dalton minimums?
For these three, the Medieval Warm Period was during the Oort solar minimum, the Spoerer was very likely warm, the Maunder cold [but cold long after the Maunder too], and the Dalton was cold provably because of volcanism, so the solar imprint is not so clear as people suppose.
Looking forwards, if the sun’s magnetic fields continue to decrease and then remain low for an extended period of time, might there be any significant impacts on Earth’s climate system?
That remains to be seen, but if we accept the PDO is going into a negative phase, any cooling might be due to that, so, again, the Sun may not have anything to do with that.
My point is not that the Sun CANNOT have an effect. It is that a solar effect has not been clearly demonstrated.

I expect that Leif might agree with Prof. Lockwood:
Prof Lockwood was one of the first researchers to show that the Sun’s activity has been gradually decreasing since 1985, yet overall global temperatures have continued to rise.
“If you look carefully at the observations, it’s pretty clear that the underlying level of the Sun peaked at about 1985 and what we are seeing is a continuation of a downward trend (in solar activity) that’s been going on for a couple of decades.
If the Sun’s dimming were to have a cooling effect, we’d have seen it by now.

“My point is not that the Sun CANNOT have an effect. It is that a solar effect has not been clearly demonstrated.”
These are both very good points and highlight the possibility that solar variability may not be a significant driver of recent and forthcoming changes in earth’s climate system. It’s possible that ocean cycles, volcanic activity, land use changes and natural variability are primarily responsible for the climactic changes “measured” over the last several centuries. The challenge in testing this and other hypotheses is that the station and proxy temperature records are compromised. As such, in order to test various alternate climate change models “we” need to build a reasonably accurate temperature record. I wonder if “we” will be able to develop a reasonably accurate temperature record using the historical station data and/or proxies, or if they are both so inaccurate that “we” are stuck waiting for the satellite record to grow…

James F. Evans (13:54:21) :
The parameters of the Empirical Scientific Method …
BTW, there is no such thing as the Empirical Scientific Method. There is only one Scientific Method. I can recommend a very good book suitable for your level: Three Steps to the Universe, by D. Garfinkle & R. Garfinkle [brothers]. They very nicely point out that there are three different universes: the Perceived Universe, the Detected Universe, and the Theoretical Universe. It is in th interaction of these three universes that scientific understanding is created. The perceived universe is what we experience every day by sound, touch, smell, taste, see. The things that we cannot detect directly, but can observe with various devices we have constructed [radio, microscope, amp-meter] make up the detected universe. If we want to understand what hoes on, we need explanations. The explanations are composed in part of the things we perceive or detect, but only in part. the rest is a set of mental constructs, known as ‘theories’. This world of purely mental creation or abstraction [almost always expressed in mathematical terms] is the missing piece. Theories serve two functions: 1st, as overarching explanations for how things work and why things happen, and 2nd as initial points of departure for exploration and creation of new ideas and knowledge. A typical example is Maxwell’s equations. The scientific process is thus circular: through theory, detection, perception, detection, and theory. The understanding lies in the theoretical part. Without that, science is just butterfly collection.
Anyway, the book is highly recommended: ISBN 0-226-28346-1, published 2008.

February 27, 2010 6:28 pm

Dr. Svalgaard:
I’m not inclined to accept your invitation to be indoctrinated.
(After all your personal attacks have failed you attempt to negotiate — you are a piece of work.)
First discussion:
“A model of magnetized plasma can be based either on a magnetic field description or on an electric field description.” — Carlqvist & Alfven
[As expressed by Maxwell’s equations where electric fields and magnetic fields have a reciprical physical relationship. Dr. Svalgaard chooses to only use the magnetic field description and exclude the electric field description. Hannes Alfven acknowledges that both descriptions are valid.] — Jim Evans
“The study of these alternative approaches (Alfven, 1968, 1979a) shows that the current description is necessary for the understanding of the formation of double layers, explosive phenomenon, and transfer of energy from one region to another.” — Carlqvist & Alfven
[Dr. Svalgaard rejects using the electric current model for understanding energy transfer from one region to another] — Jim Evans
[Double layers in plasma as Hannes Alfven stated are necessary to understand many plasma phenomenon:] — Jim Evans
http://en.wikipedia.org/wiki/Double_layer_(plasma)
Second discussion:
“I recognize the necessity of magnetic fields and their indespensible role. How may times have I cited Maxwell’s equations which speak to this requirement.” — Jim Evans
Of course, Dr. Svalgaard ignores the reality and attempts to construct a strawman argument instead of engaging in good faith discussion.
“The difference between me and Dr. Svalgaard is that he holds up the magnetic field analysis as the only scientifically valid analytical tool, purposely excluding an electric field analysis, while I stand with Hannes Alfven and note that both electric field and magnetic field analysis is valid, and, also, I stand with Alfven to state the electric current analysis is necessary to properly understand formation of double layers, explosive phenomenon, and transfer of energy from one region to another.” — Jim Evans
The scientific evidence supports Alfven, Carlqvist, Fälthammar, Peratt, and One & Mann authors of this most recent 2009 paper and the many others that support the electromagnetic approach.
Dr. Svalgaard: When you stick with your specialty, historical analysis of sunspot activity, I have no problem even if I don’t agree with your analysis — that’s science, after all — but when you engage in over the top personal attacks and then make cynical offers to indoctrinate, after the personal attacks backfired — it’s offensive.

Are we talking apples and oranges?
From the article:
“Our Variable Sun
WHICH IS KIND OF EERIE FOR EARTH LIFE DEPENDENT ON THAT SUN.
Yeah, the good thing is that when you look at what we really depend upon, which is the radiant energy from the sun – even over the full extent of the sunspot cycle, that only varies by 1/10th of 1%. So, we’re lucky in that regard. It’s a small change. If it were big, I think in terms of evolution, we wouldn’t be here talking about it. But the fact is when it comes to variable stars, our sun’s variability is tiny. Any big solar variations could really wreak havoc on our climate and survivability.”
Isn’t that the point, that the variance is only 1/10th of 1% and therefore does not correlate to Earth’s huge temperature swings let alone long ice ages that contain 10,000 year periods of warmth?

Sorry that I could not credibly be an EU theory advocate. One reason is I do not have it scoped out and probably won’t ever (so much to do and so little time). Second reason is I only have a BS in nuclear engineering (engineering science with nuclear focus) & am a loooooongggggg time out of school.
Although my wife says I can be extremely antagonistic in discussion, I am sure she does not mean in the good logical/scientific sense.

Dr. Svalgaard, we disagree, again.
Why am I not surprised?
Not wanting to be indoctrinated is totally different than not wanting to debate or present contrary arguments with supporting facts and evidence.
Although, I do agree with your discussion of the Scientific Method. My point has been that empirical observation & measurement is paramount, however, as you correctly point out, theory is important as is physical explanation. And, as you state, “initial points of departure for exploration and creation of new ideas and knowledge” is also important. I’d call these, “initial points of departure,” hypothesis.
But it’s only by testing a hypothesis through either repeated laboratory experiments or repeated in situ or remote field observations & measurements that Science validates or falsifies a hypothesis.
Hypothesis that can’t be falsified by observation & measurement is non-scientific.
I presented Alfven’s position that all components of electromagnetism need to be analyzed: Electric field, magnetic field, and electric currents.
In this thread I presented Hyder’s original paper, B. C. Low’s paper discussing filaments’ “internal electric current”, Carlqvist & Alfven’s paper discussing the electric circuit model of filaments, H. One and G. J. Mann’s paper discussing the electric circuit model of CME’s (thanks Carla for the link to the full paper), and the Abstract for Subramanian & Vourlidas’ paper discussing driving currents for flux rope CME’s.
These papers combine the factors that Dr. Svalgaard listed in his discussion of the Scientific Method, hypothesis, observation & measurement, theory, and physical explanation.
As impressive as the physical spectacle of the huge filament is upon viewing, to Science it’s just as important to understand & explain the physical processes (know what we are viewing).
Hopefully, the above papers have helped do that.

Tom in Florida,
The Earth’s climate depends on solar activity for the very simple reason that there is nothing but the Sun to warm the Earth.
Long-time correlation between the Earth’s climate and the Sun activity may be very complex, because the Earth is a very complex system with a multitude of oceanic, atmospheric, and biological feed-backs and lags, but it’s there. Every winter is colder than summer, and every night is colder than midday. Any change in Earth’s insolation results in a change of Earth’s temperature. We have no explanation of how exactly it happens — there are too many variables, and not enough data — but it doesn’t mean that it doesn’t happen.
If the minuscule amount of data gathered up to date “doesn’t support” the obvious in the eyes of people who prefer not to see the woods for the trees, it means that the data is insufficient but in no way confutes the obvious.

OK, we then start. First we need to establish some facts based on observations. Filaments [and prominences = filaments seen at the edge of the Sun] can last for weeks. They are cool clouds suspended in the hot corona by magnetic fields. The clouds condense out of the corona and although the matter seems to ‘hang’ there for weeks, it is really a very dynamical phenomenon: the material is continually falling down onto the surface, but being replaced by new material condensing out of the corona. This is seen clearly in this video: http://www.youtube.com/watch?v=mZkJcAB2aSQ
1: they are cool because we can see them in lines of Hydrogen
2: they are suspended temporarily by magnetic fields as can be seen from the gracefully curved field lines lit up by the material.
3: gravity is pulling the material down [as it always does no matter where].

A tutorial is less useful, because most people’s attention span is not large enough [we are all busy, right?]. The short ~100 word exchanges seems to be a better format. And since we start out with ‘filaments’, the current thread seems appropriate. Let’s see how the experiment turns out.

February 28, 2010 8:25 am

Suranda (03:36:32) :
A number of commenters have indicated a desire to have Dr. Svalgaard expand on his views seemingly in a lecture style format (I’m paraphrasing)– Dr. Svalgaard lectures and readers accept his view-point.
But if the view-point starts with a faulty premise and builds on erroneous assumptions then all it does is lead readers astray from understanding the actual physical reality.
Dr. Svalgaard’s starting premise (based on past discussions/debates) is primarily mechanical: “hot gas”, fluid dynamics, “wind”, and gravity are Dr. Svalgaard’s starting premise.
Which would be appropriate in a physical environment consisting of neutral gas, liquids, and solids. But the solar environment (assuming that is what Dr. Svalgaard would concentrate on) does not consist of neutral gas, liquids, and solids, rather, it is over 99.99 % plasma.
(And in terms of the Sun — even Dr. Svalgaard won’t deny the 99.99% figure.)
Indeed, the physical relationship between the Sun and the Earth is dominated by plasma dynamics (excluding the constant of gravity which maintains the orbit, obviously, an important element).
As the Sun is over 99.99% plasma, its processes are dominated by plasma dynamics.
What dominates plasma dynamics?
Well, as all readers, here, know, plasma consists of charged particles, free electrons & ions and the physical relationships of these charged particles are dominated by the fundamental force of electromagnetism.
Caveat: Yes, temperature, velocity, and gravity still play a role, but within an overarching electromagnetic environment.
Until Dr. Svalgaard comes to terms with this physical reality, and it seems he still hasn’t (many of his premises are pre-space age), his indoctrination will fail to be intellectually fruitful for understanding the physical reality of our Sun or the Sun/Earth physical relationship — which is important for understanding the Earth’s climate.
The Sun is a plasmoid: Plasma-Magnetic-Entiy.
Dr. Svalgaard rejects the plasmoid term, but what have observation & measurement informed Science about the Sun’s nature?
The Sun is over 99.99% plasma, magnetic fields are ubiquitous in the Sun’s immediate environment, and Maxwell’s equations tell us that where there are magnetic fields, there will be electric fields. And sophisticated modelling and observation & measurement demonstrate electric currents play a powerful role — indeed, CME’s the most disruptive “event” to Man’s technology are giant plasma flows of electrical current.
That’s why CME’s are so disruptive to Man’s electromagnetic technology.

Since there were no objections or questions [feel free at all times to return to points you want clarified or objects to – I’ll number all conclusions], I’ll press on.
4. From these observations [and from theory – Alfven’s discovery] it is clear that the plasma at least at times is trapped or tied to the field lines – as it doesn’t fall down right away.
5. Since gravity pulls the plasma down, there is a downwards force which is balanced by the magnetic force holding the plasma up [at least temporarily]. The net result is a deformation of the magnetic field as seen in one of the Figures at the top of the page: http://www.ips.gov.au/Images/Educational/The%20Sun%20and%20Solar%20Activity/Solar%20Flares/hyderflr.gif

Very cool quote from Leif. Trouble with that is half the temperature data collection has missing wings. And in some cases, entire butterflyies are missing. But no problem.

7. The ‘coronal rain’ [seen in the video] drains the filament at a rate sufficient to deplete the whole corona within a few hours.
8. Those two observational results imply that there is continual circulation of plasma that readily condense [because space is basically cold] into the prominences. And that the equilibrium that allows the filament to exist as a structure [even though its material is continually recycled] is a dynamic one played out as the interaction of magnetism and gravity.

James F. Evans (08:25:16) :
And in terms of the Sun — even Dr. Svalgaard won’t deny the 99.99% figure.
In the solar photosphere the degree of ionization is only 1 part in 10,000 or so. Thus 99.99% is not ionized at all. If you adopt the convention that ANY partially ionized medium is a plasma no matter how small the degree of ionization is, then the Sun would be 100% plasma, but so would ordinary sea water [which incidentally has the same electrical conductivity as the solar photosphere].

February 28, 2010 9:43 am

Painful explanation of the obvious is a very successful evasion tactics.
However, the noticeable warming of Earth in the second half of 1990s followed the noticeable increase in solar activity. And the currently observed noticeable cooling of Earth follows the prolonged quiet period in solar activity.
If Earth’s temperature is completely independent of solar activity, as Dr. Svalgaard stipulates, how does he explain this correlation? Or would he rely on patently falsified CRU data to claim that currently there is no cooling?

February 28, 2010 9:44 am

Reviewing what Dr. Svalgaard has listed (up through 8 points) notice not once does he refer to electric fields or electric currents.
This is fundamentally wrong and does not reflect empirical observation & measurement (as stated in the scientific papers I provided) or even theoretical premises such as Maxwell’s equations (which were formulated and verified by empirical observation & measurement) which clearly state by mathematical equations that magnetic fields and electric fields are reciprical (you can’t have one without the other).
Dr. Svalgaard uses the term “rain”.
This is instructive to his view-point: “rain” is a code-word for mechanical physical relationships, it’s a reference to neutral matter fluid dynamics, “rain” has no meaning in terms of electromagnetic phenomenon.
In terms of the Sun’s dynamics, it’s an obfiscation.
At this point, it’s important to note I invited Dr. Svalgaard to challenge and refute the conclusions of the Carlqvist & Alfven and the One & Mann peer-reviewed papers, both discuss and explain the electric circuit model of solar filaments — Dr. Svalgaard failed to either challenge or refute these two papers.
When a scientist can’t respond to scientific papers that contradict his opinion that is evidence that his opinion can’t encompass the observations & measurements provided or the conclusions stated in the papers.
Therefore, that should be taken into consideration when deciding how much weight to give that scientist’s opinion or as Dr. Svalgaard like to say, “assessment”.
“A model of magnetized plasma can be based either on a magnetic field description or on an electric field description.” — Carlqvist & Alfven
“The study of these alternative approaches (Alfven, 1968, 1979a) shows that the [electric] current description is necessary for the understanding of the formation of double layers, explosive phenomenon, and transfer of energy from one region to another.” — Carlqvist & Alfven
Filaments and their development into CME’s is a transfer of energy from one region to another, and often is an explosive phenomenon. And, as Alfven has stated the release of energy by CME’s is accomplished by electrical double layers.
Dr. Svalgaard will you respond to the two papers provided or will you ignore them?

Stick around, pay attention, and observe the format.

Possibly this will help clarify the magnetism/plasma/electric components of the Sun ~ written by a beautiful Australian woman back in 2004:
“The principle upon which the sun operates is simple, and in its simplicity rings the truth of how it functions. The common belief that the sun is a huge sphere of gases that collapsed upon themselves and began burning a mixture of gases as a “nuclear furnace” is erroneous.
Instead, the Designer placed a huge material cube into space and set the cube into motion. This motion is a speedy, spinning, gyrating motion that revolves upon a SINGLE POINT in the centre of the cube (slightly off centre point). This POINT should NOT be construed as meaning a single axis that runs through the cube, but instead it should be viewed as a single point in the middle of the cube.
The motion spins the cube (sun) so rapidly that its corners appear to touch nearly all points of the perceived sphere, thus giving the illusion that the object in the sky is a sphere. By analogy, consider that a fan has blades, but when it is set into fast motion, the blades of the fan seem to disappear and an illusion is created which makes the blades look like a circle. This illusion can also be seen in airplane propellers, which also appear to be circles as the propellers spin rapidly. It should also be mentioned that at various speeds, the circles of the propellers seem to change their direction of rotation. This two-dimensional circular type of illusion is the principle behind the cubed-sun’s three-dimensional illusion that it is a sphere and that the sphere is rotating.
However, the sun appears to be aflame, while propellers and fan blades do not. This is partly because the Designer created gravity, which attracted particles of atmosphere to the cube (sun). These particles of air were thereafter trapped by the sun’s gravity and forced to stay with the cube. The flaming sun is primarily due to the vast differences in velocities of the spinning of the objects. Thus, the sun’s atmosphere blazes while the fans’ and propellers’ do not. When the cubed sun spins ferociously fast, it creates a great deal of friction coupled with the fact that the 12 “sharp” edges and 8 “hard” corners of the cube heighten the friction.
The apparent rotation of the sun on an axis has been called “differential rotation” because it appears to take 25 days for the sun to rotate around its equator and 35 days at its poles. This has erroneously been accepted by science as a phenomenon of a gaseous sphere. It is actually an illusion that the sun has a spheroid rotation. This is much like the example of the spinning fan blades. The spinning cube gyrates in such a way that it appears that there is a sphere and that the sphere is rotating irregularly. Thus, an illusion of a differential rotation is created by the spinning cube.”
Possibly we’ve been taught all the wrong science about the nature of the Sun!
I hope you’ll forgive my rant here Dr Svalgaard and Mr Evans, but maybe this is why you guys have a difference of opinion.

C’mon, even you must know that is a function of Earth’s tilt and has nothing to do with solar activity.

Not true, besides you are talking about weather. Are you suggesting that if I sit in a chair at noon and stay there til midnight the temperature change is due to change in solar activity and not the Earth’s rotation moving me out of direct sunlight?
“Any change in Earth’s insolation results in a change of Earth’s temperature”
Changes in insolation are overwhelmingly due to the conditions of Earth. Changes in the orbit, obliquity, cloud cover, aerosols all result in insolation changes. If you held your uncovered arm out in the direct sunlight in June in Florida you would feel intense heat. If you move into the shade that intense heat goes away yet the Sun didn’t do a thing.

Dr. Svalgaard, do you have a peer-reviewed paper (or any paper) that offers authority for your assertion?
You shouldn’t be appealing to authority all the time [and I’m your authority on this]. Independent thinking and understanding are much better. The extremely weak degree of ionization of the photosphere [and of the interstellar gas too, BTW] has been known for almost a century [since Saha published the Saha Equation in 1920], so this fact you will today find in textbooks rather than derived in peer-reviewed modern papers [find me a recent peer-reviewed paper purporting to convince people the Earth is round]. So people simply refer to the weak ionization as the well-known fact it is. Here is a modern paper doing just that: http://www.leif.org/EOS/2000JA000005.pdf scroll to page 23,155 [top line]. You will also in that paper see how the motions of the photospheric plasma across magnetic fields help generate the electric currents that propel the CMEs [as we shall also see later on in the thread].
include the corona, as that is where much of the energy that comes from the Sun to the Earth is generated which in turn warms the Earth.
The corona shines with an intensity less that 1/1000,000 of the photosphere so does not heat the Earth measurably.
Dr. Svalgaard, do you dispute the assertion that the corona is 99.99% ionized plasma?
Absolutely, it is 100% ionized plasma.

You are on the right track.
NASA had something to say in this regard just recently:
“February 5, 2010: For some years now, an unorthodox idea has been gaining favor among astronomers. It contradicts old teachings and unsettles thoughtful observers, especially climatologists.”
“The sun,” explains Lika Guhathakurta of NASA headquarters in Washington DC, “is a variable star.”
Dr. Svalgaard’s response was to call this statement “hype” and offer a century old paper which did conclude the energy of the Sun was variable.
To make sure I’m not taking Dr. Svalgaard’s comment out of context let me lay out that context:
Evans (12:14:48) 2/20/10 quoted NASA: “February 5, 2010: For some years now, an unorthodox idea has been gaining favor among astronomers. It contradicts old teachings and unsettles thoughtful observers, especially climatologists.”
“The sun,” explains Lika Guhathakurta of NASA headquarters in Washington DC, “is a variable star.”
Dr. Svalgaard (12:32:50) 2/20/10 responed: “This is just the usual NASA hype and this is nothing new or unorthodox or contradictory. Abbot showed this 100 years ago:
http://www.leif.org/EOS/Abbot-Variation-Sun.pdf
Riccioli claimed that much in 1651 and Herschel in 1801.”
The paper is good and I’m happy Dr. Svalgaard presented it.
But one paper, while it can set out the physical reality, does not speak for an entire community, as Dr. Svalgaard would likely be quick to point out in reference to the papers I presented, here, in this comment thread. NASA’s statement about “solar constant” was reflecting the “consensus”.
Any internet Google search for “solar constant” will bring up a whole list of hits for “solar constant” and discussions concluding there is a “solar constant” of energy output of the Sun.
NASA was clear: The prevailing consensus was wrong.
(What does that say about the possibility that other astrophysics’ “consensus” is wrong?)
Indeed, Dr. Svalgaard’s position that solar acitivity has little or not impact on climate rests on the assumption of a “solar constant” of the Sun’s energy output.
This is a good example of the consensus being wrong. Consensus does not trump physical reality — and physical reality can be demonstrated by one set of observations & measurements (one scientific paper).
What is amusing about this is that Dr. Svalgaard’s long-held position that .1% change in TSI between solar minimum and maximum does not make a difference in Earth’s climate is directly contradicted by one of the NASA scientists.
And, as the NASA scientist makes clear TSI is more than infrared:
“Astronomers were once so convinced of the sun’s constancy, they called the irradiance of the sun “the solar constant,” and they set out to measure it as they would any constant of Nature. By definition, the solar constant is the amount of solar energy deposited at the top of Earth’s atmosphere in units of watts per meter-squared. All wavelengths of radiation are included—radio, infrared, visible light, ultraviolet, x-rays and so on. The approximate value of the solar constant is 1361 W/m2.”
“‘Solar constant’ is an oxymoron,” says Judith Lean of the Naval Research Lab. “Satellite data show that the sun’s total irradiance rises and falls with the sunspot cycle by a significant amount.”
“At solar maximum, the sun is about 0.1% brighter than it is at solar minimum. That may not sound like much, but consider the following: A 0.1% change in 1361 W/m2 equals 1.4 Watts/m2. Averaging this number over the spherical Earth and correcting for Earth’s reflectivity yields 0.24 Watts for every square meter of our planet.”
“Add it all up and you get a lot of energy,” says Lean. “How this might affect weather and climate is a matter of—at times passionate—debate.”
This would seem to directly contradict Dr. Svalgaard’s position and falls in line with numerous other scientist’s observations & meaurements and conclusions.
Sometimes, I wonder if Dr. Svalgaard plays both ends against the middle depending on what discussion he is in.
Remember, just because Dr. Svalgaard says something doesn’t make it right.
Hold Dr. Svalgaard to the same standards you would hold any other scientist to.

February 28, 2010 11:41 am

About ‘plasma’. One can adopt the definition that any mixture of positive, negative, and neutral particles is a plasma. This is perfectly reasonable and is often done. With this definition, it doesn’t make sense to state that the Sun is 99.99% plasma. The Sun is 100% plasma, but so is sea water. We usually do not consider sea water to be a plasma, reserving the word for a medium with a high temperature. Because a plasma contains electrically charged particles [even if only in very small concentrations like in the solar photosphere], a plasma interacts with electromagnetism. Because 5/6 of the observable universe does not, at least 5/6 of the observable universe is not a plasma, under any definition. What does ‘observable’ mean? It means that it is ‘detectable’ using suitable devices like telescopes, magnetometers, our eyes, etc. If we use our eyes [eventually augmented by a telescope or photographic plate or a CCD] to detect a change in the position of a star as the Sun passes near it in the sky, that is an ‘observation’ and the star is a part of the observable universe as is the body [the Sun in this case] that causes the deflection.

February 28, 2010 11:52 am

The Onel & Mann paper [being the newest] says:
“Due to the photospheric plasma motion [with velocity u across the magnetic field B] the Lorentz force q u x B acts on the charges q of the plasma and leads to generation of an electric current”.
This is the mechanism that I have been trying to make you understand for months now [‘ad nauseam’]. I really wish you were not so education-resistant.

February 28, 2010 12:07 pm

Dr. Svalgaard:
No, with all due respect, you aren’t my authority.
However, I appreciate the paper you provided to support your assertion regarding the ionization percentage of the Sun’s photosphere.
But, upon review that paper doesn’t provide any discussion of observations & measurements which support that position. It makes an unsupported assertion, just like your unsupported assertion.
Please provide a paper that discusses observations & measurements which relate and shed light on the ionization level of the photosphere of the Sun.
Again, I’m open-minded about it, but I have to see observation & measurement and analysis & interpretation that comes to that conclusion.
I will state that with the Sun’s photosphere at roughly 5,800 degrees Kelvin, which seems could support a lower level of ionization, but count me from Missouri, “the show me” state.
Introduction to Plasma Physics: With Space and Laboratory Applications, by Donald A. Gurnett, Published 2005, Cambridge University press:
“It is an interesting fact that most of the material in the visible universe, as much as 99% according to some estimates, is in the plasma state. This includes the Sun…”
So, no, not all textbooks take it for granted that the Sun’s photosphere has a low state of ionization percentage.

“If photospheric motion in the presence of magnetic fields produces voltage differences […] a current starts to flow”.
again, this is the mechanism that I have been trying to make you understand for months now [‘ad nauseam’].
Perhaps we can put those two papers to rest now. Or do you have more that show the same thing that you want to have confirmed?
The important issue that mechanical forces, gravity and temperature [kinetic energy] push plasma across magnetic field lines and thereby generate electric currents with all the phenomena that flow from that. This is the way Nature works as Carlqvist, Alfven, Onel, Mann, and thousands of other scientists know so well, and as all our emiprical evidence shows.

9. The delicate balance between gravity and the magnetic field can be upset in several ways, e.g.
10. A new active region can emerge nearby, adding to or disturbing the existing magnetic field [like twisting the support of the hammock you a relaxing in]
11. Alfven waves travelling up the legs of the magnetic field [caused by twisting/movements of the foot points by the photospheric plasma pushed around by convection can also upset the balance and add energy to the configuration.

Dr. Svalgaard (07:28:12) wrote: “They [filaments] are cool clouds suspended in the hot corona by magnetic fields.”
I missed this reference.
Again, “clouds”, like “rain” is a mis-nomer. Reference to “clouds” is an obfiscation which obscures the electrical nature of a filament, and, again, “clouds” is code-speak to fluid dynamics in neutral matter.
But a filament is not neutral matter, it is plasma, charged particles, which respond to electromagnetic forces.

Leif Svalgaard (07:28:12) :
OK, we then start. First we need to establish some facts based on observations. Filaments [and prominences = filaments seen at the edge of the Sun] can last for weeks. They are cool clouds suspended in the hot corona by magnetic fields. The clouds condense out of the corona and although the matter seems to ‘hang’ there for weeks, it is really a very dynamical phenomenon: the material is continually falling down onto the surface, but being replaced by new material condensing out of the corona. This is seen clearly in this video: http://www.youtube.com/watch?v=mZkJcAB2aSQ
1: they are cool because we can see them in lines of Hydrogen
2: they are suspended temporarily by magnetic fields as can be seen from the gracefully curved field lines lit up by the material.
3: gravity is pulling the material down [as it always does no matter where].
Leif Svalgaard (08:32:10) :
Leif Svalgaard (07:28:12) :
Since there were no objections or questions [feel free at all times to return to points you want clarified or objects to – I’ll number all conclusions], I’ll press on.
4. From these observations [and from theory – Alfven’s discovery] it is clear that the plasma at least at times is trapped or tied to the field lines – as it doesn’t fall down right away.
5. Since gravity pulls the plasma down, there is a downwards force which is balanced by the magnetic force holding the plasma up [at least temporarily]. The net result is a deformation of the magnetic field as seen in one of the Figures at the top of the page: http://www.ips.gov.au/Images/Educational/The%20Sun%20and%20Solar%20Activity/Solar%20Flares/hyderflr.gif
Leif Svalgaard (09:15:25) :
Leif Svalgaard (08:32:10) :
6. The total mass in a [or just a few] large filament is comparable to that in the rest of the corona.
7. The ‘coronal rain’ [seen in the video] drains the filament at a rate sufficient to deplete the whole corona within a few hours.
8. Those two observational results imply that there is continual circulation of plasma that readily condense [because space is basically cold] into the prominences. And that the equilibrium that allows the filament to exist as a structure [even though its material is continually recycled] is a dynamic one played out as the interaction of magnetism and gravity.

How would we know if we were less or more than halfway to understanding the universe?
Granted that some people do not understand even the tiniest bit of the universe, the appropriate answer is that ‘it is turtles all the way down’.

At some point, the turtles rest on assumptions about which way is down, and how far “all the way” is.

February 28, 2010 4:29 pm

The Onel & Mann paper [being the newest] says: “Due to the photospheric plasma motion [with velocity u across the magnetic field B] the Lorentz force q u x B acts on the charges q of the plasma and leads to generation of an electric current”.
Dr. Svalgaard (11:52:37) :”This is the mechanism that I have been trying to make you understand for months now [‘ad nauseam’]. I really wish you were not so education-resistant.”
the Carlqvist & Alfven paper
says [page 204]: “If photospheric motion in the presence of magnetic fields produces voltage differences […] a current starts to flow”.
Dr. Svalgaard (12:18:00) : “again, this is the mechanism that I have been trying to make you understand for months now.”
Actually, Dr. Svalgaard, neither paper says what causes this motion. You assume it does, but that’s not what the papers say.
Read the quotes you provided from the papers, no mention of “gravity” or “temperature”.
Now, it’s true both are present at the surface of the Sun, the photosphere, but temperature (random atomic motion) with any corresponding increase in temperature (increase in random atomic motion) tends to dissipate magnetic fields because magnetic fields are caused by organized charged particle motion.
Temperature is unorganized, random atomic motion. That’s why a iron magnet will lose it’s magnetic field when heated.
These observations tends to discount Dr. Svalgaard’s hypothesis.
Gravity is an attraction toward a central point, not a side to side motion. But gravity is a fundamental force and present in all bodies with mass.
So, these two factors don’t spring out as reasons for the initial motion, but I do state a caveat:
I have already raised the idea of plasma without motion as a isolated hypothetical and as a hypothetical condition in the Sun in prior posts.
Evans (11:39:02) 2/24/10: “… because plasma does not want to stand still (the law of entropy) a kind of Biermann battery mechanism is effected, yes, a type of internal dynamo where the plasma wants to unwind, this causes the motion of plama and resulting magnetic fields and possibly the rotation of the Sun. These flows of plasma and their self-sustaining magnetic fields collide with other magnetic fields and charge-seperated electric currents result.”
Yes, the Biermann battery mechanism, a type of internal dynamo.
So, this is nothing new to me as you incorrectly imply with your comment.
Seems like another one of Dr. Svalgaard’s strawman arguments, he puts up from time to time in order to make himself look good.
So, no it is not an idea that you have been communicating for “months, now” that I have been resistant to.
Dr. Svalgaard, I appreciate the paper you provided which states in part:
“Ionization in the sun and universe In the photosphere of the sun, the mass density is ~3 􀀁 10–4 kg/m3 which corresponds to 2 􀀁 1023 protons/m3 (mp = 1.67 􀀁 10–27 kg). Since this is substantially larger than the 50% density (42) for T = 6400 K, the plasma must be more than 50% neutral. Indeed, one can impose the criterion nr+1 + nr = 2 􀀁 1023􀀁m–3 onto (40) to find that nr+1/nr = 4 􀀁 10–4 at 6400 K; it is mostly neutral.”
This is a theoretical exercise and one worth exploring.
But the paper goes on to state its own caveat:
“In the dilute gases often found in astrophysics, the temperature required for ionization is quite low. Once an atom is ionized, it has few opportunities to become neutral again; an interaction with a free electron is required and these are rare in a dilute gas”.
This passage would seem to contradict the first passage and open the door to a higher level of ionization at the surface of the Sun, the photosphere.
And, another caveat: Discussions about the “beginning of the Universe” are meaningless — Man is not privileged to know how the Universe started, not withstanding a lot of guess work surrounding the so-called “big bang” hypothesis.
But all this is a diversion because that’s not where I started — this is where I started:
“The moving plasma, i.e., charged particles flows, are currents that produce self-magnetic fields, however weak.” — Dr. Anthony L. Peratt, Los Alamos National Laboratory
“An electromotive force [mathematical equation] giving rise to electrical currents in conducting media is produced wherever a relative perpendicular motion of plasma and magnetic fields exists.” — Dr. Anthony L. Peratt, Los Alamos National Laboratory
And, that is where the Carlqvist & Alfven paper started and where the One & Mann paper started. And, when pressed, you acknowledge.
So, Dr. Svalgaard, why do you obfiscate with words like “rain” and “cloud”? And, why do you carry on without mention of electromagnetic forces?
Evans (13:16:21) : “But a filament is not neutral matter, it is plasma, charged particles, which respond to electromagnetic forces.”
Dr. Svalgaard (14:13:13) responded: “Plasma is neutral…”
Plasma can be quasi-neutral, with equal numbers of free electrons & ions in random distribution.
But, when plasma flows, you get:
“The moving plasma, i.e., charged particles flows, are currents that produce self-magnetic fields, however weak.” — Dr. Anthony L. Peratt, Los Alamos National Laboratory
“An electromotive force [mathematical equation] giving rise to electrical currents in conducting media is produced wherever a relative perpendicular motion of plasma and magnetic fields exists.” — Dr. Anthony L. Peratt, Los Alamos National Laboratory
Plasma can and often does take the form of charged-seperated, charged particles, in other words, electric current.
Again, Dr. Svalgaard, the two papers make quite clear the filaments are plasma animated by electric currents.
Why are you so resistant to this proposition?
I’ve been trying to teach you this for months…but you refuse to learn…
Why?

Suranda,
Thank you for leading into a favorite subject of mine.
I would rather use the concept of identity instead of concept of limit in assessing homo sapiens capability to know the universe.
It is one thing to say man’s knowing capability has a specific nature [like everything that exists has a specific nature], it has a fundamental identity. We can know only within the specific nature of our knowing facility. However, it is another thing entirely to say there is a limit to what we can know. To state we have knowledge of limits of knowledge [things we cannot know] implies one already has knowledge of what cannot be known, so inherent error in the statement itself.

Temperature causes convection which is a very organized motion, with hot stuff rising and cold stuff sinking.
Gravity is an attraction toward a central point, not a side to side motion.
Gravity causes a river to flow 1000 miles towards the sea. But, apart from that, the gravity that create currents does that by pulling downwards and forcing the plasma across horizontal magnetic field lines [see you Low paper you quoted].
Yes, the Biermann battery mechanism, a type of internal dynamo.quoting yourself?
The Biermann battery effect does not operate in the Sun.

It does not. It is very specific about that. The 6400K was about the Universe.

He knows, nevertheless. You may not know. That is a problem with you.

And, that is where the Carlqvist & Alfven paper started and where the One & Mann paper started. And, when pressed, you acknowledge.

Not when pressed. This is what I have always said: move a conductor across a magnetic field and you generate a current.
So, Dr. Svalgaard, why do you obfiscate with words like “rain” and “cloud”? And, why do you carry on without mention of electromagnetic forces?
We use descriptive words without being confused by them, like the solar ‘wind’, and as I said whenever a conductor is moved across a magnetic field, e.g. falling down like rain [that is pulled by gravity] an electric current may be generated [if there are charges to carry the current.
Plasma can be quasi-neutral, with equal numbers of free electrons & ions in random distribution.
Not ‘quasi’. As long as there are equal numbers, it is neutral. Salt dissolved in water has equal number of Na+ and Cl- ions and is very neutral.
Again, Dr. Svalgaard, the two papers make quite clear the filaments are plasma animated by electric currents.
Science does deal with animated matters. The two papers very clearly [as I shoqed by quoting the relevant passages, that it motions of the plasma generate the currents, and that therefore the currents are consequences rather than causes. One can, of corse, call that ‘animation’ as long as it is clear what causes what.

This comment gives Dr. Svalgaard’s game away (why he is so bound & determined to deny the electrical current flowing in the filament).
The “twisting” magnetic fields are consistent with the behavior of magnetospheric Birkeland currents which Science understands & accepts are electric currents.
The electromagnetic dynamics of the Birkeland currents cause them to rotate like giant tornadoes. There is no “feet” twisting them to cause the morphology of “twisted ropes”.
Dr. Svalgaard’s point 9 and 10 are a predicate to justify so-called “magnetic reconnection”, a pre-space age (1946) speculation.
You see Hannes Alfven identified these filaments as often stretching into flares or CME’s where explosive release of energy occurs. And Alfven identified the filaments as electric currents, or “the electric circuit model”, seconded by the One & Mann electric circuit model and also, modelled double layers as the cause of the explosive release of energy.
“The study of these alternative approaches (Alfven, 1968, 1979a) shows that the current description is necessary for the understanding of the formation of double layers, explosive phenomenon, and transfer of energy from one region to another.” — Carlqvist & Alfven
See plasma double layer:
http://en.wikipedia.org/wiki/Double_layer_(plasma)
But to allow that the filaments are electric current (and behaving as electric currents which twist and show a morphology of twisting magnetic fields), then opens up the door to Hannes Alfven’s Electric Double Layer as the mechanism for the release of the energy and not so-called “magnetic reconnection”.
Title: The Alfven-Carlquist double-layer theory of solar flares
Authors: Hasan, S. S. & Ter Haar, D.
Journal: Astrophysics and Space Science, vol. 56, no. 1, June 1978
Partial Abstract: “We discuss the applicability of this theory [The Alfven-Carlqvist double layer theory of solar flares] to solar flares, and show that conditions in solar flares may be such that double layers can exist…”
“These particles will be accelerated in the double layer and may in this way account for the production of high energy particles during the impulsive phase of solar flares.”
I’m sorry, But Dr. Svalgaard’s ‘lecture” is designed not to inform the readers of the physical relationships of filaments, but to justify and protect the failed “magnetic reconnection” model.
That is why Dr. Svalgaard has given the the electric circuit model short shrift (acknowledging the filament’s electric current when pushed into a corner, but quickly going back to his mechanical model, so that double layers can be ruled out and so-called “magnetic reconnection’ can be justified).
It makes one shake their head — this is not science, this is protecting a failed theory (and most likely protecting grant money).
Again, Dr. Svalgaard’s points 9 and 10 have no basis in physical reality other than to justify a failed theory.
Flowing electric current causes twisting magnetic fields — Science knows that from the study of magnetospheric Birkeland currents that have a twisted magnetic field and are known to be charge-seperated, charged particle flows, electrical currents.
From NASA:
“A “magnetic rope” is a twisted bundle of magnetic fields organized much like the twisted hemp of a mariner’s rope. Spacecraft have detected hints of these ropes before, but a single spacecraft is insufficient to map their 3D structure.”
Solar flares also have a helical twisted morphology.
And, it is not because they are mechanically twist at the feet but that thoughout the entire circuit of the electric current there is twisted magnetic field.
Recently, twisted magnetic fields have been detected below the surface of the Sun.

“The quasineutral plasma model proposed by Langmuir more than 75 years ago is still widely used today and is based on two approximations: charge neutrality and the Boltzmann relationship for electrons.”

9. The delicate balance between gravity and the magnetic field can be upset in several ways, e.g.
The “twisting” magnetic fields are consistent with the behavior of magnetospheric Birkeland currents which Science understands & accepts are electric currents.
The ‘twisting’ was meant as one way of generating Alfven waves. I could have said ‘plucking’, ‘shaking’, ‘bobbing’ or any number of words indicating motion. The currents in the filaments are not Birkeland currents. And Birkeland currents are not ‘tornadoes’ [word used by someone objecting to ‘clouds’ and ‘rain’…].
As I said, the magnetic configuration can be disturbed by many things, all involving bodily movement of the plasma in the photosphere, eventually followed by reconnection in the corona to create a new topology of the field.
One more time: as Carlqvist, Alfven and everybody else who knows anything about this, electric currents are very much involved. Without they nothing would happen. The currents [as Alfven said] are generated by motion of the plasma across magnetic field lines and are thus consequences rather than causes of the filament. Let me quote again: “photospheric motion in the presence of magnetic fields produces voltage differences […] and a current starts to flow”. Note that the motion precedes the current. Onel & Mann: “Due to the photospheric plasma motion [with velocity u across the magnetic field B] the Lorentz force q u x B acts on the charges q of the plasma and leads to generation of an electric current”.
What can be more clear as to what causes what?

February 28, 2010 7:41 pm

Leif Svalgaard (12:29:03) :
OK, so now we can continue.
12. The falling plasma [see http://www.youtube.com/watch?v=zbPNcjj__iE&feature=related ] cross the horizontal magnetic field lines. They can do this in spite of the frozen-in condition because they are cool and the ionization is only partial.
13. a conductor crossing a magnetic field generates an electric field. The force equation is F = q(E + v x B), from which we get the electric field E = F/q – v x B; http://en.wikipedia.org/wiki/Lorentz_force
14. a current will now flow. Since the quantities are vectors they have a direction. With v vertically down [gravity], B horizontal [has to connect two opposite polarities in the photosphere, E will be perpendicular to both, i.e. along the filament.
15. Magnetic field on the sun are often twisted and have a weak helical structure. This ‘helicity’ is opposite in the two hemispheres [and does not change with the changing polarities of the solar cycle] and is likely caused by the solar dynamo twisting the field [Hurricanes also twist oppositely in the two terrestrial hemispheres].
16. So filaments often have a slight twist to them. The twist actually helps stabilize the filaments a bit.

February 28, 2010 7:49 pm

James F. Evans (19:08:53) :
is based on two approximations: charge neutrality and the Boltzmann relationship for electrons.
Charge neutrality means neutral. And [as the paper you cite says] the Boltzmann relationship is unnecessary and is not always justified.
These are just words. The physics is that if you take a macroscopic volume there are no measurable difference between the number of positive and negative charges. If there were, the resulting strong electric field would short out immediately, restoring neutrality. Here is the definition of charge neutrality: “The approximate equality of positive and negative particles in high-density plasmas.This phenomenon, which is sometimes called electrical neutrality, is a result of the extremely large electric space charge fields that would arise if the densities were not equal. Although the positive and negative charge densities are seldom exactly equal, their percentage difference is so small as to be negligible. It is not difficult to maintain this condition in an active plasma since ionization or recombination always produces or destroys an ion pair together.” This will hold even more in low-density plasma as the mobility of the particles are much higher.

February 28, 2010 9:59 pm

Leif Svalgaard (19:41:37) :
OK, so now we can continue.
17. If the change in the magnetic topology is rapid enough, the current generated by the change can be very strong and lead to vigorous heating of the filament with resulting rapid expansion into the corona, a coronal mass ejection [CME].
18. The CME rises, but gravity resists the expansion initially. However gravity gets weaker with height and the gravitational restriction is gradually lifted and the CME eventually reaches supersonic speeds and escapes into the solar wind.
19. In spite of this escape, the magnetic field lines frozen into the CME are still firmly rooted in the photosphere even as far away from the Sun as the Earth, resulting in a long ‘magnetic tongue’ reaching far out in the heliosphere.
