Must Watch Solar Flare Video - Stunning Detail!

Solar Flare Must Watch!

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-arc-rains-fire-on-sun-magnetic-solar-flare-loop-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
Dave

 

[Drakkith]

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

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

 

[davenn]

where did you read that date ? I must need new glasses


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

definitely new glasses haha

 

[Drakkith]

And at the top of the article too.

:tongue:

Nice.

"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://Earth'sky.org/space/auroras-widely-seen-july-14-chance-on-july-15-too
and NASA.. http://www.nasa.gov/mission_pages/sunearth/news/News071212-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'sDave

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

I have reason why I was killjoy to some celestial art connoisseur in a [/PLAIN] 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 [/PLAIN] 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 ??

cheers

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.

 

[Matterwave]

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!

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?

 

[Bandersnatch]

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.

 

[Jonathan Scott]

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!

"NASA's Solar Dynamics Observatory (SDO) and Solar and Heliospheric Observatory captured September 10th, 2014's X1.6-class flare and ensuing coronal mass ejection (CME)." http://www.space.com/27107-powerful-solar-x-flare-pointed-at-earth-video.html
http://www.space.com/27126-solar-flares-northern-lights-displays.html

Powerful solar flares from the sun this week may amplify the northern lights displays over parts of the northern United States through the weekend, space weather scientists say.

The forecast for potentially supercharged auroras comes after powerful solar storms fired off eruptions of solar material, first on Monday (Sept. 8), then again on Wednesday (Sept. 10). During Wednesday's solar flare, the sun unleashed a major X1.6-class flare directly at Earth. While aurora activity could spike overnight tonight (Sept. 11), the best chance of strong northern lights displays along the northern U.S. states will be Friday night.

Some pretty awesome images of the sun and it's flares.

SOLAR STORM UPDATE: The first of two CMEs expected to hit Earth's magnetic field on Sept. 12th has arrived, and a minor (G1-class) geomagnetic storm is underway as a result of the impact. The second and potentially more powerful CME is still en route. NOAA forecasters say geomagnetic storming could become strong (G3-class) during the late hours of Sept. 12th and Sept 13th after the second CME arrives.

The next CME, now only hours away, was launched by an X-class flare, so it is potent. However, not every potent CME produces a potent geomagnetic storm. It all depends on the inner magnetic architecture of the CME, which is unknown until the CME actually arrives. NOAA forecasters are estimating a 45% chance that strong magnetic disturbances will reach mid-latitudes on Sept 13--almost like a coin toss.
