guys and gals

if you haven't seen this video of solar flare yet, then hold onto your seats!!
make sure you view it in full screen mode


http://www.space.com/19873-blazing-a...oop-video.html

I have seen many flare videos over the years but the detail in this one is truly stunning
the best I have ever seen

unfortunately, due to no date given, I don't know when this video was taken

cheers

That was awesome! Never ever seen one like that before!

Edit: The flare occurred on July 19th, 2012.

edit: DUH right near the start
ya know I had played that twice before and didn't see that

definitely new glasses haha

You might like to bookmark this site.. http://spaceweather.com/
or find "NOAA NWS Space Weather Prediction Center" in your favorite social media network for information when not to trust your GPS or unplug your electronic device especially if you don't have surge protector, among other info.

"The arrival of the CME shook Earth's magnetic field, which in turn induced electrical currents in the ground at Arctic latitudes."

Nice, you found the time machine of the site. The CME from July 19 eruption in the OP did not hit Earth, but July 12 eruption did.. Earthsky reported it too.. http://earthsky.org/space/auroras-wi...on-july-15-too
and NASA.. http://www.nasa.gov/mission_pages/su...X1.4flare.html

been there for a good number of yrs
I have been into solar activity since long before the internet existed
Was routinely doing sunspot drawings and aurora observations from the early '70's

Nice to know that someone is interested in Heliophysics . And to feel at ease to mention an on-going research about Flux Transfer Event .

I have reason why I was killjoy to some celestial art connoisseur in a discussion about aurora last year in other science site. It's history anyways and though my question in there was unanswered, the news about the recent launch of SWARM came to me as a consolation.

My jaw literally dropped when I saw the Earth scale model! What's with that big bright flash between 3:33-36 at around 1'oclock...lightning? Does that even happen on the sun?

I had to play it a few times to catch what you were referring to
hard to say what it was ... another brief bit of flaring or maybe an artefact with the digital imaging ??

I believe the movie was made by taking exposures over several hours, so the quick flash was probably an event several minutes long. Still not sure what it was though.

Are those pieces of plasma really going so fast as to move from the top of the flare to raining down on the sun in a matter of seconds, or am I seeing some kind of heat/shock wave? If those are the actual bulk motions of the plasma, then those particles appear to be traveling well in excess of 10,000km/s which is 1/30 c! o.O

EDIT: Wait, Drakkith says it's a long exposure...so they aren't moving as fast as I thought...any estimates on the speeds then?

From what I've read, typical bulk motion of plasma in solar flares is in the vicinity of 150-300 km/s at the flare onset(in some cases as high as 1000km/s). Lower for long-lived flares. The velocities quickly decay to 30-60-ish km/s.

Google "solar flare non-thermal plasma velocities" and you'll find some papers discussing the observations.

Does anyone know the approximate time compression factor involved in the NASA timelapse movies of solar flares?

I'm guessing that stuff unfolds slowly over hours, whereas in sci-fi movies or even documentaries it happens in similar time to the timelapse movie!
