SDO First-Light Briefing
Launched on Feb. 11, 2010, SDO is the most advanced spacecraft ever designed to study the sun and its dynamic behavior. The spacecraft will provide images with clarity ten times better than high definition television and more comprehensive science data faster than any solar observing spacecraft in history.

[Note: Insiders tell me that some of the images from the spacecraft show exquisite details of material streaming outward and away from sunspots. Other SDO photos show extreme magnifications of activity on the sun’s surface, such as pores. The spacecraft also has made some high resolution measurements of solar flares in a broad range of extreme ultraviolet wavelengths. The images are stunning I’m told. I’ll post them here as soon as they are available. – Anthony]

I think that I went to school with Dianne Micks. She hadn’t two halfpennies to rub together and now she has an Observatory.
This is awesome, looking forward to seeing the images. I have studied the Sun for a long time and I recall when I was about 8 years old, while listening to teachers’ story time at primary school, I was doodling the Sun and a solar flare. My teacher, obviously annoyed that I wasn’t paying attention to the story, called me up to his desk to see what I was doodling. He was a bit surprised when he looked at it and after I described what it was.
This is a good thing. The images should advance understanding of
solar processes by an order of magnitude.
Too bad today’s (Wednesday) sun is a bald as a billiard ball:

Will Dave Hathaway be there to comment ?
This will be most interesting,,,, and fun too!

During this month sun is not having the forecasted behaviour
as you can see here
http://www.solen.info/solar/images/solar.gif
and in the SIDC
http://www.sidc.be/html/wolfjmms.html
Figures that there would be no sunspots the day they unveil SDO.
It’s the Watts Effect.
Amateur Astronomers know this as the New Telescope Effect: You buy the scope of your dreams, get it home, and it rains for 3 months straight.

GEE, Solar cycle 24 was real short! /Sarc
Yesterday, SDO, took image number one million.
Leif Svalgaard (04:11:09) :
Is it like a real-time frame where they are capturing all day long?
Gail Combs (03:41:02) :
It hasn’t exactly behaved like solar cycles we’ve been used to seeing the last 100 years. I expect it to roll down a bit then back up.
I don’t know a thing about SDO, sorry to say. Since it has photos, one ought to be able to measure temperature or at the very least contrast across sunspots. Does it have spectroscopic instruments?
The real question – Leif, what does this mean for Bill Livingston’s fading sunspot measurements? I imagine he must be delighted to look at brightness/temperature data of sunspecks without the atmosphere getting in the way. Does he have any special time on SDO, or is the data he needs just coming as a matter of course?
And, while I have the floor, what does Bill say about the recent bigger spots of SC24 so far?
rbateman (04:36:07) :
Is it like a real-time frame where they are capturing all day long?
Yes, at a rate of 150 Megabytes per second ALL the time [equal to half a million mp3 songs per day].
Ric Werme (04:43:21) :
Does it have spectroscopic instruments?
It is one big spectrograph.
what does this mean for Bill Livingston’s fading sunspot measurements? […] the data he needs just coming as a matter of course?
Just rolling in.

When you compare apples to apples, it seems to be doing a pretty good job of imitating Solar cycle 5, at least for the first third of cycle 5. http://www.landscheidt.info/?q=node/50
See it as it happens:

If the Solar Wind speed were to fall below a threshold, it can stop. Here is a report on what happened May 10-12, 1999.
http://science.nasa.gov/science-news/science-at-nasa/1999/ast13dec99_1/
“Scudder and Fairfield theorized, the “strahl” electrons would flow unimpeded along the Sun’s magnetic field lines to Earth and precipitate directly into the polar caps, inside the normal auroral oval. Such a polar rain event was observed for the first time in May when Polar detected a steady glow over the North Pole in X-ray images.”
“According to observations from the ACE spacecraft, the density of helium in the solar wind dropped to less than 0.1% of its normal value, and heavier ions, held back by the Sun’s gravity, apparently could not escape from the Sun at all.”
Where are current measurements of the Solar Wind’s speed and density?
Wonderful. proper science. We dont mind paying taxes for this sort of thing

Sounds a lot like they figured out technology advances with each new satellite launched. I would hope is does.
Good. Because at the center of the climate issue is a unexplained warming trend in the 80’s to middle 90’s which required an explanation which was back filled in with manure by Gore & Co. called AGW. The unexplained bit is the difference between Leif’s and others observations that the sun has a .1K variance from angry to dead pan where a 1K input is needed to explain the warming trend (which has since decoupled). There has been a very interesting discussion of the TSI issues and others on a thread here at WUWT titled LEVY WALKS. Missing from the Sun-climate equation is a ‘mechanism’ a mysterious X-Force for which TSI is supposed to be a proxy? FYI————->
————————————————————-‘…………….LEIF to Nicola Scafetta (18:16:48) :
Scarfetta:
really? You surprise me! So, after all the sun is not constant (plus a 11-year cycle)!
LEIF:
If you would care to actually read my papers you would have been less surprised. In http://www.leif.org/research/The%20IDV%20index%20-%20its%20derivation%20and%20use.pdf you would find [paragraph 20]:
“[20] The 11-year running mean (green line) of B over the period hints at the 100-year wave (±15%) often seen in solar activity and proxies thereof [Gleissberg, 1939].”
Do you believe the TSI was completely and perfectly constant during that period?
No, we do not believe that anymore. TSI at each solar minimum returns to the same value, so we surmise that it also did that during the MM. On top of that there would a ~12.5-yr smallish solar activity component. Cosmic ray modulation was considerable during all Grand Minima [that occur at random, BTW], so the magnetic cycle was still operating. Why sunspots were not seen, is unknown, but their magnetic field could have sunk to just below 1500 Gauss, which would cause them to be effectively invisible. Something like that may be happening right now, e.g. http://arxiv.org/PS_cache/arxiv/pdf/1003/1003.4281v1.pdf……….’
And this:
‘…………………(from) Nicola Scafetta (19:11:08) :
(to) Leif Svalgaard (18:45:09) :
“Since TSI [or the mysterious X-force for which it is supposed to be a proxy] does not have any long-term trend [c.f. what I told you above], then what is that ‘astronomical influence’?”
It is not true that solar activity does not have any long-term trend. Notice that I always use the TSI proxy models as approximate proxy of a generic solar activity. Nothing exclude me to use some other solar proxy for the purpose.
Do not be impatient about the exact mechanism! before or later it will be found but the signal is there and also strong. Just, I do not believe that there is only one mechanism at work………….’

Sort of the other way around. When we have new technology, new satellites are launched.
This is really interesting stuff. Thanks for the comments. Will be fun to watch it live stream. (Well for a couple of minutes anyway.☺)
When can we expect NASA to make dire predictions of something based on these new intensive sun observations going back a few days now? And, of course, WE are to blame. Keep Hansen away from this. ☺ ☺
It will be a racist hoax if one picture does not include a giant thermostat for God.
@ur momisugly Mark Adams also at http://www.spaceweather.com/ upper left hand corner.
I’m looking very much forward to this and will keep my copy of “Sunshine (2007)” ready for dessert, a silly movie but with some very impressing images of the sun
