Lots of minor activity in AR 2661 (animations)

[GreatAttractor]

I've had a fruitful weekend: good seeing (for 90 mm aperture, that is), crystal clear skies on Friday, and equally good seeing on Saturday with 1/3 cloud cover miraculously sweeping sideways from my location since morning to 4 pm. Too bad I caught only one stronger C-class flare in AR 2661 in all those hours.

Everything captured with a 90 mm refractor with Lunt 50 etalon, PGR Chameleon 3 mono (ICX445), processed with Stackistry and ImPPG, showing AR 2661.

Overview shot of AR 2661 on Friday morning:

Friday, 30-s intervals, 0:53 h and 1:06 h. Lots of small-scale activity, too bad it wasn't exactly on the limb as on Thursday; the spikes and surges would look even better (as in http://astrob.in/262196/B/):






Saturday, 30-s intervals, 2:15 h total. A class C2.1 flare peaked at 9:57 UTC (preceded by a few smaller events around):

And the whole material from Saturday on fast forward (5-minute intervals, 4:45 h total), showing the changing aspect as the Sun rotates:

Alexandra, I export the GIF from GIMP. It's convenient for any final cropping/scaling, and has a playback function (Filters/Animation/Playback...).
