Solar storm continues, geomagnetic storm and auroras expected

We have about three hours to go for the expected arrival time of the CME at 0625 UTC/1025 PM PST. Proton flux remains high as do other indicators. Additionally another C class solar flare just occured.

This bulletin just in from NOAA SWPC:

2012-03-08 03:18 UTC  Solar Radiation Storm Continues, Geomagnetic Storming Expected

The coronal mass ejection (CME) associated with the R3 (Strong) Radio Blackout event from 0024 UTC March 7 (7:24 p.m. EST March 6) is forecast to pass ACE early morning UTC on March 8 (start of day EST March 8). Geomagnetic storm periods reaching the G3 (Strong) level are likely as a result.  Additionally, the Solar Radiation Storm levels remain above the S3 (Strong) threshold at this time. Region 1429 remains potent and subsequent activity is certainly possible. Updates here as conditions warrant.

http://www.swpc.noaa.gov/rt_plots/Xray.gif

UPDATE: 825PM

I’ll know more once the CME particles pass the L1 point where the ACE satellite is station-keeping, of course that only gives me a few light seconds warning…but the CME particles are moving much slower than lightspeed, it will be at least a few minutes depending on how fast they are traveling.

Since POES is down for terrestrial computer maintenace, I’m watching the OVATION aurora forecast model right now, but it doesn’t get very accurate until particles pass the L1 point and ACE relays the data…if the solar wind is too strong, ACE saturates the sensor and the forecast gets barmy. http://helios.swpc.noaa.gov/ovation/ Image below updates every 10 minutes.

This is also useful to watch, when it spikes, CME has hit L1

And Leif recommends this plot, MAG- SWEPAM plasma:

UPDATE: 2012-03-08 15:03 UTC  Geomagnetic Storm has Started, Solar Radiation Storm Continues

The coronal mass ejection (CME) associated with the R3 (Strong) Radio Blackout event from 0024 UTC March 7 (7:24 p.m. EST March 6) arrived at ACE at 1045 UTC today (5:45 a.m. EST March 8).  So far the orientation of the magnetic field has been opposite of what is needed to cause the strongest storming.  As the event progresses, that field will continue to change.  Based on overall strength, the predictions for periods reaching the G3 level look justified.  Additionally, the Solar Radiation Storm levels remain above the S3 (Strong) threshold at this time, with values rising momentarily with shock arrival.  Region 1429 remains potent and subsequent activity is certainly possible. Updates here as conditions warrant.

  1. Based on the magnetic configuration of 11429, the CME magnetic field will be pointing South when it hits the Earth. This would predict a strong storm.

    I either read somewhere or had a hallucination that during these kinds of events, residents of orbiting space craft actually see flashes of light in their closed eyes as the hydrogen nuclei scintillate inside of the eyeball. Pretty wild stuff when you consider all the micro electronics around you being shot full of charged particles.
    I can’t imagine being violated by high energy protons, can’t be good for you DNA either.

    @mark wagner
    North Bay and Sudbury are not too far off the beaten track from TO (Ontario) but even that’s often on the southern limits for araura viewing. Have seen them there though, summers, winters and even from inside the smaller city of North Bay.

    It must be substantial if it can spike voltages in our power grids.
    Can anyone convert it into an everyday measurement ?

    The effect is really only seen on the more northerly Transmission Lines (NOT ‘grids’ really as the public fashionably likes to sling it these days) and on the longer runs of Transmission lines; the damage is the DC caused by the changing Geomagnetic field which induces GICs (Geomagnetic Induced Current) into the lines, causing magnetic flux changes in the transformers which may then ‘saturate’ on 1/2 of the cycle of the applied AC voltage, and the transformers have a specific BH curve (flux density- field intensity) that should not be exceeded, adding DC current to the AC already there causes the problem … when in saturation, the current level in the transformer can soar, no longer inhibited by counter a EMF which would be present were the transformer not in a magnetically saturated condition due to the added GIC.

    Flares are one thing [and their energy can be measured and is known], but what concerns effects on the Earth, the important piece is the solar wind hitting us. The appendix [pages 31ff] of http://www.leif.org/research/Geomagnetic-Response-to-Solar-Wind.pdf has a calculation of the energy flux impinging on the Earth during a magnetic substorm [and a geomagnetic storm is just a sequence of several of those]. The result is 3 Terawatt.

    Wiki gave me this:
    A solar flare is a sudden brightening observed over the Sun surface or the solar limb, which is interpreted as a large energy release of up to 6 × 10^25 joules of energy[1].

    On my napkin, I did a quick conversion and I got 16.7 million x 1 billion KW hours.
    That could power a few homes…

  18. GeoLurking says:

    Ref: _Jim (above).

    This is also similar to the mechanism of some of EMP, though the energy levels are smaller and much more localized.

  19. GeoLurking says:

    Grrr….. meaning the EMP effects are on a much smaller scale. (could be read the other way, which is not what I meant)

  20. DJ says:

    Does the sudden increase in proton flux translate into corresponding atmospheric chemical changes…ie sulphur dioxide, methane hydroxyls, etc.,,, and a change in clouds that could be connected? (perhaps not unlike the GCR theory)
    It would seem to me that the electrical concerns are only a part of the equation, and the climate or at least short term weather is influenced in some way.

  21. [snip - sorry - wayyyy off topic, electric motors - Anthony]

  22. kbray in california says:

    I calculated it to be enough electricity to power every household in the USA for 6 years.
    One rogue flare can do that…
    I hope the sun stays “happy” for a long time.
    If the earth is warming or cooling, the first suspect to look at has to be “El Sol”.
    It’s the obvious.

  23. southern auroras are spectacular when viewed from the adelaide hills, south australia.
    during 1981, we saw one so bright that we thought it was a dreaded bushfire burning over the hill. we drove to the top of the hill, only to find that it seemed to be burning over the next hill ! we watched it for quite a while. it seemed to cover the whole sky, and reminded me of the massive curtains being pulled accross at the movies.

    Although Dr. S. doesn’t favour it, the Tromso magnetogram has clearest indication of the magnetic field disturbances
    Tromsoe is in the auroral zone and shows mainly local disturbances, not representative for geomagnetic storms, and thus prone to over-interpretations. This is particularly evident now since the CME hasn’t hit yet. Use Kakioka or Boulder or Guam, but not Tromsoe. This is not about favoring, but about doing things right. I have mentioned this several times and you still haven’t learned.

  28. BTW, the energetic protons have already arrived. They travel a lot faster than the solar wind CME protons, and arrives in minutes or hours, rather than hours and days.

  30. Kelvin Vaughan says:

    In the 1960s I used to work in the international telegraph centre in London. On one floor of the building were the teleptinters working over HF radio circuits. There were thousands of teleprinters chattering out their messages from all over the world. The noise was deafening.

    As a solar storm hit the ionosphere the radio circuits would drop out one by one depending on the frequency being used. Slowly the room would get quieter and quieter as the teleprinters ceased to function until there was an eerie silence in the room. After some minutes a teleprinter would start to chatter away again, then one by one they would all start working and the room would build up to the full deafening noise again.

  31. I am following this on my simple webpage where I have assembled several on-line graphs, etc. This is intended only for myself and a few friends interested in aurora photography. (Small webserver on a Synology DS210j).

I once heard a saying that goes like this ” If the stars only came out once every 10 years, no one would miss it. ” …much as with solar eclipses, people fly all over the world to see it in person. Enjoy the show folks..

  35. mark wagner says:

    @Ldd: Thanks! So if it’s a good storm, I could fly into Ontario, take a car north and just wait until dark. Maybe.

  36. So, the solar wind magnetic field was northwards, therefore no strong magnetic storm. There was a strong compression of the magnetosphere, called the ‘initial phase’ when the CME hit: http://www.swpc.noaa.gov/rt_plots/bou_12h.html but the ‘main phase’ that should occur a few hours later is basically missing.

    Is that the total energy involved with a flare? (Considering variable parameters e.g. size, duration of event, magnitude, etc)

    Then one must work out the ‘propagation’ of that energy involving the inverse square law to determine the amount of ‘energy’ impinging on the earth (after considering conversion effects from the local event into the CME charged particle motion energy), and more specifically, the amount of ‘energy’ (in the form of a mag field) intercepted by a length of ‘wire’ comprising a HV Transmission line.

    Actually, the shell of the spaceship is pretty good shielding from the high energy protons. BUT, not against normal COSMIC rays. THEY can cause the flashes, at about any time..all the time. Typical exposure is about 10 to 100 mR per day, indicating that long term (2 to 3 year) stays will need more shielding for radiation health physics reasons! (Mars mission?)
    I can’t imagine being violated by high energy protons, can’t be good for you DNA either.

    Ref: _Jim (above).

    This is also similar to the mechanism of some of EMP, though the energy levels are smaller and much more localized.

    The high-frequency spectral energy content (rate of change) is much higher with an EMP event whereas the GICs (Geomagnetic Induced Currents) indicate to be low-frequency, changing or varying over time periods of seconds to tens of seconds. The rate of change is important, as well as the amplitude of the magnetic amplitude change, induced voltage being proportional to effective Inductance times the rate of current change (v = L * di/dt).

    So in general, is it difficult to predict the polarity ahead of the CME arrival at ACE?
    Yes, indeed it is. My estimated based on the photospheric field was clearly wrong. Of course, one should base the prediction on the coronal field rather than on the underlying photospheric field. This is the holy grail of this business, and progress is being made in calculating the coronal field. No doubt, this event will be studied closely.

  43. MAVukcevic says:

    Forbush decrease (about 10%, still falling) in progress

    is a rapid decrease in the observed galactic cosmic ray intensity following a coronal mass ejection (CME). It occurs due to the magnetic field of the plasma solar wind sweeping some of the galactic cosmic rays away from Earth (ref. wiki)
    Good test for the Svensmark hypothesis, if decrease lasts day or two. Take note of the current cloudiness forecast for next two days, then compare with the actual events.

  44. Jim G says:

    Nothing like the national news to keep up with science. Fox news reported the CME on its way at 4 million miles per second. I thought the speed of light was 186,000 miles per second? Guess it has changed or this stuff has gone superluminal. Einstein will be upset over this.

    Don’t forget about lunar positioning and the orbital positions of the inner planets, What effect can the moon have on incoming CME particles? if the moon was positioned between the Earth and the sun could it deflect or absorb the CME particles in some way to reduce the overall effects of the incoming solar storm on Earth? maybe a kind of geomagnetic solar eclipse??

    It’ll be interesting to check where the Moon and planets were after each solar storm passes during this solar maximum and note their intensity,

    Jim,

    I used the figures from the wiki link below…
    (consider the source)

    http://en.wikipedia.org/wiki/Solar_flare

    It sounds like a measurement of the total flare energy to me.

    I was also very generous with 60 KWH per day per household to allow for 100% electric homes, and for Al Gore being a power pig. 1800 KWH per month is a bit much. Dividing that amount by a more standard usage would give a multiplier to the 6 years I estimated. It was a ballpark figure to give perspective. I see estimates anywhere from 500 to 900 KWH per month per household… except Al Gore’s homes use over 20 times the average. (Everybody is equal, but some are more equal than others… as they say.)

    Using a double or triple, providing I didn’t lose a decimal point in my coffee somewhere… the 6 years of electricity for all US households could extend out to 12 or 18 years for the wiki described flare. That is impressive.

    The amount of energy that actually hits the earth directly is suggested above by Leif Svalgaard which he says is a much tamer 3 Terawatts that affects the earth. Your calculations may vary.
    I wanted a visual image of how much energy the flare represents. 10^25 is hard to register.

  51. Brian H says:

    @mark;
    Depending on how far west you are, it would be better to fly into Winnipeg, Regina, or Edmonton. (Clear skies in the forecasts would be the thing to look for.) They are quite a bit further north. (In fact, the southern border of the western provinces is almost 3° latitude north of North Bay or Sudbury!) Then head for the northern edge of the urban areas, so your back is to the city lights.

    Only a VERY small part of the flare energy hits the Earth. For a visual image, consider this: we get solar energy measured by the Total Solar Irradiance, TSI. When a major flare occurs, TSI goes up VERY little. In fact barely measurable: http://www.nature.com/nphys/journal/v6/n9/full/nphys1741.html

    http://sprg.ssl.berkeley.edu/~hhudson/presentations/soho23.090924/tsi_flares_poster.pdf

    “Even the peak flux of the biggest solar flares contributes to less than 0.1 % of the TSI. Only one X17 flare (October 28th, 2003) has been unambiguously detected in any of the TSI measurements made to date”

  53. kbray in california says:

    “The amount of energy that actually hits the earth is a much tamer 3 Terawatts. ”

    A lightning bolt can peak at 1 Terawatt.
    3 lightning bolts directly into the power lines could get your attention.

    4 million miles per second ?
    MSM… again, consider the source…
    Lots gets distorted there.
    They must be in a hurry.
    4 million miles per hour fits reality better.

    The Earth has a surface area of 196,939,900 square miles.
    That would be a Richter 8 every 2 square miles of the entire surface of the planet including ocean floor. Intersecting shock waves would amplify each other.
    That would certainly send us back to the stone age… brutal.

  66. Bill Parsons says:

    Another question (anyone knowledgeable about the physics):

    The neutron monitors at the south pole show a spike in GCRs mid-day yesterday (Wednesday) prior to a precipitous drop-off. None of the other monitors show this spike.

    Leif, don’t these plasma masses tumble or rotate as they travel through space? How can they be deemed “north-pointing” or “south-pointing”?
    They do not tumble as they have their magnetic field lines still rooted in the Sun. North is the direction generally pointing perpendicular to the Earth’s orbit [more precisely to the plane that contains the Earth's magnetic equator] to the Pole Star, south is the other way. If the solar wind magnetic field points in a northerly direction, we say it is ‘northwards’. The opposite for south.

    March 8, 2012 at 3:44 pm
    Leif, don’t these plasma masses tumble or rotate as they travel through space? How can they be deemed “north-pointing” or “south-pointing”?
    They do not tumble as they have their magnetic field lines still rooted in the Sun [on their side]. A cut through the CME ‘flux rope’ may look something like this cartoon: http://www.leif.org/research/Sun-CME-Earth.png When the cloud reaches the Earth there will be a front anda back side with oppositely pointing fields. So since we have have northward fields for a while and the storm fizzled out because of that, we should now get the back side field which is southwards, so a magnetic storm may ensue.

Typical exposure is about 10 to 100 mR per day, indicating that long term (2 to 3 year) stays will need more shielding for radiation health physics reasons! (Mars mission?)
    I can’t imagine being violated by high energy protons, can’t be good for you DNA either.

    Max, Now I’m really curious, because methinks a 100+Mev proton might have a chance to penetrate the shell of said spacecraft, I’m sure you’re correct vis a vis cosmic rays

    Leif,

    Thanks for your explanation regarding the plasma field’s polarity. Regarding my second question…

    BTW, the energetic protons have already arrived. They travel a lot faster than the solar wind CME protons, and arrives in minutes or hours, rather than hours and days.

    Was this what caused the neutron monitor spike in Antarctica mid-day yesterday (7th)?

    No. Several stations had a spike, and some not. Space is a messy place. The solar wind is gusty and variable from place to place.

    Forbush decrease (about 15%, still falling) in progress

    strongest I have seen in the recent years, for the moment is not working in the UK

    It should be good global test for the Svensmark’s hypothesis.

    Apollo astronauts reported seeing light flashes beyond the protection offered by the Earth’s magnetic field.

    http://lsda.jsc.nasa.gov/books/apollo/s4ch2.htm introduction in part:

    Crewmembers of the Apollo 11 mission were the first astronauts to describe an unusual visual phenomenon associated with space flight. During transearth coast, both the Commander and the Lunar Module Pilot reported seeing faint spots or flashes of light when the cabin was dark and they had become dark-adapted. It is believed that these light flashes result from high energy, heavy cosmic rays penetrating the Command Module structure and the crewmembers’ eyes. These particles are thought to be capable of producing, visual sensations through interaction with the retina, either by direct deposition of ionization energy in the retina or through creation of visible light via the Cerenkov effect.

    Crewmembers of Apollo 12 and 13 were questioned concerning this phenomenon during postmission debriefings. All reported the ability to “see” the flashes with relative ease when the spacecraft was dark with their eyes either open or shut. The Apollo 12 Commander stated that “There were big bright ones all over,” and added that he had not seen anything similar during his two Earth-orbital Gemini missions. The Commander of the Apollo 13 mission also observed these flashes but could not remember seeing them during his earlier Apollo 8 mission.
