This DVD of movies is a compilation of flares taken at various wavelengths, including white light, 171A, etc.
So, I downloaded and burned the DVD a while ago, and I just checked it.
Now supposedly I am to look at something at 30 minutes and 4 seconds.
I guess it is at "play all movies" (combined X Flares part 1, part 2, filament flares, flare evolution) let me click on it and see if I can get to 30:04.
At 29:30 images of a sunspot (I knew the Sun was Dutch!!), orange sun, black spots, gray umbrae
At 30:00 we see the spot rotating to the limb.
At 30:04 .... nothing
Guess I am watching the wrong movie?
Oh, in an earlier message it is at 30:10, 30:56 and 45:15
At 30:10 the spot has reached the limb
At 30:30 the movie changes to flares nice arcades building up at the beginning something "shoots away" at 30:32
At 30:40 change to green showing an loop and bright footpoints and some kind of streamer.
At 30:41, the loop has evolved into an arcade. This arcade is dynamic, but little emission in it, the flows seem to take place mainly in the lower shorter loops. Interesting to see.
at 30:52 change to orange again and sunspots near the limb.
at 30:56 nothing just a sunspot going to the limb
Let's go to 45 minutes
at 45:00 a black and white image of a sunspot going to the limb and as it reaches the limb there seems to be emission "around" the sunspot at 45:08
at 45:30 change to Xray emission from loops, showing flows through the loops (i.e. moving bright blobs along the field lines)
at 45:49 a nice build up of a large loop
at 45:58 something that looks like a flare
then lots of activity in the magnetic loops, "flaring" and "throwing plasma around" and as it it a top view of the action, we cannot really see what is happening completely, although there are events that appear to eject stuff upward, which "blind" the camera now and then.
It's facinating to watch all that activity and some of the things can probably be described by Alfvén's "unwinding of the flux tube" and some can be described by the Kaastra model of a flare.
at about 50 mins there is a side view of a region with loops. a nice build up of an arcade until 52:09 or so and then an explosion with stuff being ejected upward, out of the image (i.e. away from the sun), and the rest of the loops are short again, in agreement with the Kaastra model. At the same time there is activity in the smaller loops, maybe in agreement with the Alfvén model.
Note that there seem to be large explosions that eject matter but it gets "bend around" further away. This is because some of these flaring loops are covered with larger arcades that are virtually devoid of plasma, but will stop some of the ejecta and lead them back to the "surface" of the Sun.
So, what exactly was I supposed to be looking at here?
I am sure I am interpreting it all completely wrong.
