Re: MEGA SOLAR FILAMENT; let's observe this one
Dec 06 update:
A magnetic filament snaking around the sun's SE limb just keeps getting longer. The portion visible today stretches more than 700,000 km--a full solar radius. NASA's Solar Dynamics Observatory took this picture during the early hours of Dec. 6th:

Re: MEGA SOLAR FILAMENT; let's observe this one
Wow, SDO is providing some incredibly detailed images. It looks like the filament shorted out against the top of the photosphere resulting in an exploding double layer perhaps? However, it seems to have merely produced a moderate CME for such a large filament. It wasn't directed towards Earth so we shouldn't expect any geomagnetic effects.
cheers
Nitai, have you looked at any of the other data besides the real-time simulations? Geomagnetic activity has been very quiet the past couple of days. We didn't even get a boost in x-ray flux other than a weak B-class flare that may or may not be related. Everything else is pretty much flat-lined as well and that shouldn't change any time soon. Anyhoooo, just a friendly reminder to consider all of the relevant data.From SpaceWeather.com:
Earth was not in the line of fire; the cloud should sail wide of our planet. Earth-effects might be limited to pretty pictures.

Re: MEGA SOLAR FILAMENT; let's observe this one
I watched the STEREO-A video from spaceweather.com yesterday and there was a very large bright object in the final frame. Today however that bright object is gone from the video.
I wish I had clipped a picture from the video. Perhaps someone else saw it. It may have been just a flaw, but it is interesting that they went to the trouble to remove it.

Larger image:The structure of a magnetic flux rope. In the interior the magnetic field is strong and axial. The magnetic pressure gradient force pushes outward, balanced by the curvature force of the twisted field around the axis. Currents flow to maintain the twist. If the current flows solely along the magnetic field, the structure is termed force-free (after Russell and Elphic, 1979).

I'm wondering if it was a filament/corona interaction that destabilised
the flux tube, or if it was a snapping of the central magnetic tension lines
leading to an unwinding of the outer layers, which is what I am tending to see
after watching the event a few times. Just speculating.

Re: MEGA SOLAR FILAMENT; let's observe this one
BrigitBara, you mean the bright spots at the left of the image? They show up near the very end in one or two frames at the time of maximum brightness in the eruption. It took a few attempts to pause the vid at the right time but I did manage to get a screenshot.
To me it looks like a "lens flare" in the camera optics.
Seems to have produced a bigger CME than I had thought initially, probably a little stronger than average rather than the "epic blast" announced in the headlines.
GaryN, thanks for that info.
cheers

Re: MEGA SOLAR FILAMENT; let's observe this one
It takes 3 to 6 days before a CME hits the earths ionosphere, if it is going to hit us at all.
Something completely different; this 'magnetic field line' snapping' produced a magnetic storm in the ionosphere, right? To say it otherwise, does any electric discharge produce a magnetic pulse? Or let me say even differently.
If I had a setup of a plasma antenna at one side and an electric discharge sparc plug at a 100 feet on the other side, could the magnetic pulse be measured within the plasma of the antenna? Does this experiment represent a plasma model of the ionosphere - sun interaction?

Re: MEGA SOLAR FILAMENT; let's observe this one
Very nice capture, thank you! It could be something grainy/imperfect in the imagery as you say. I do think it was more brilliant and lasting in the first video release, and appeared to be possibly a sungrazer.solrey: They show up near the very end in one or two frames at the time of maximum brightness in the eruption. It took a few attempts to pause the vid at the right time but I did manage to get a screenshot.
A third explantion is that I have discovered yet another of my mental superpowers: to spot these practically subliminal frames in STEREO CMEs. That's good!

Not sure wether that is a merely rhetorical question you posed,
but anytime there is a arc-spark near an (unshielded) radio receiver, it will be heard, meaning an EM radiation was created; and of course the stronger the E, the more of the M.
Is it a "plasma model of the ionosphere - sun interaction?"
Good question.

Re: MEGA SOLAR FILAMENT; let's observe this one
No, not a rhetorical question - I was trying to come up with some kind of model you could test in the lab. You could compare the properties of the plasma lab model with those of the sun. The earth's capacitor property is missing in my plasma antenna model however.seasmith wrote:MrAmsterdam,If I had a setup of a plasma antenna at one side and an electric discharge sparc plug at a 100 feet on the other side, could the magnetic pulse be measured within the plasma of the antenna?

Dec. 13, 2010: On August 1, 2010, an entire hemisphere of the sun erupted. Filaments of magnetism snapped and exploded, shock waves raced across the stellar surface, billion-ton clouds of hot gas billowed into space. Astronomers knew they had witnessed something big.
It was so big, it may have shattered old ideas about solar activity.

http://science.nasa.gov/science-news/sc ... leruption/Explosions on the sun are not localized or isolated events, they announced. Instead, solar activity is interconnected by magnetism over breathtaking distances. Solar flares, tsunamis, coronal mass ejections--they can go off all at once, hundreds of thousands of miles apart, in a dizzyingly-complex concert of mayhem....
Researchers have long suspected this kind of magnetic connection was possible. "The notion of 'sympathetic' flares goes back at least three quarters of a century,..

Re: MEGA SOLAR FILAMENT; let's observe this one
Do you suppose there is any way, after a week or two goes by, to correlate such a large-scale event on the Sun with activity at the edge of the plasmasphere (via any of our 'bots on the fringe out there)? o.O

I think the one at 12/12 , 0500 GMT, might have topped this one.

Re: MEGA SOLAR FILAMENT; let's observe this one
Oh the irony.
Lead story on Spaceweather.com about the August 1 eruptions:
Reminds me of some of the sungrazers that have triggered a smallish CME on the opposite side of the sun followed by a larger CME in the vicinity of the sungrazer. Hmmm. Could the curvature of the spherical electric field/double layers around the sun act like a concave reflector that focuses electromagnetic waves of a certain frequency/amplitude back inward/sunward to trigger CME's on the opposite side of that sphere?
cheers
Lead story on Spaceweather.com about the August 1 eruptions:
Then the third and last story, still up from yesterday, is about the most recent multiple eruption.GLOBAL ERUPTION ROCKS THE SUN: A global eruption on the sun has shattered old ideas about solar activity. Researchers presented their surprising findings at a press conference yesterday at the American Geophysical Union meeting in San Francisco. Get the full story from Science@NASA.
In the most recent event on Dec. 12, notice how CME's 2 and 3 occur along respective lines opposite from the "anchors" of a semi-horseshoe shaped CME#1. The southern anchor of CME#1 is mostly centered on a line with CME#2 in the northern hemisphere, while the northern anchor of CME#1 (just north of the solar equator) is mostly centered on a line with CME#3 in the southern hemisphere. They seem to be related to me. SDO images will probably show those three CME's were connected somehow.TRIPLE ERUPTION: Solar activity surged on Sunday, Dec. 12th, when the sun erupted three times in quick succession, hurling a trio of bright coronal mass ejections (CMEs) into space. Coronagraphs onboard the Solar and Heliospheric Observatory recorded the action: Click here to play a 9 MB gif movie
A preliminary analysis suggests that none of the CMEs will be geoeffective. The expanding clouds should miss our planet.
Are these CMEs related? According to images from NASA's twin STEREO spacecraft and the Solar Dynamics Observatory, the clouds emerged from three distinct blast sites separated by great distances. In each case, a magnetic filament erupted--one near the sun's southeastern limb (CME#1), one near the north pole (CME#2), and one on the far side of the sun (CME#3). Because all three eruptions occurred within a matter of hours, the coronagraph images suggest a single 3-lobed cloud; in fact, they are distinct CMEs.
