Encouraged by an M-class flare in AR2871 earlier this week, I dutifully captured data for a time lapse, alas, not much has happened. A minor C1.0-flare at 11:30 UTC and a B7.2 at 12:04 UTC, also a part of the upper filament lifted off at some point. 30-second intervals, 4:45 h total:

Wonderful, love the animation, it looks like the chromosphere rips open below the AR as that flare builds up!

Philip, great, super! Congratulations on the spod! Your wonderful mod takes amazing pictures. Thanks for the animation, almost 5 hours! How many frames did you take and put together for these photos?

These are very nice. I like how the Ha ones clearly show the disturbance in the chromosphere around the active regions.

Thank you, everyone.

Ivan, 560 videos (249 GiB) went into the animation. I'm still using PGR Chameleon 3 at the moment, so just 900 frames per video at 45 fps. But even after fully transitioning to the Blackfly-S, I won't capture more data for the 90 mm setup, as the current approach works well enough. Stacking (with Stackistry) took some time, my Ryzen 7 2700 (8C/16T) managed about 68 videos/hour. But the subsequent batch processing and alignment in ImPPG took only a few minutes.

I'm not uploading it to Astrobin for now, because an animated GIF was >170 MiB. A H264/5 Mbps video (which I linked above), on the other hand, is < 10 MiB (and at this data rate it preserves all details). I'll wait for Salvatore to enable MP4 uploads, he said it might come next year. (I'm not uploading to YT/Vimeo either, as they recompress the videos and degrade the quality a lot.)

BTW, I have another long animation like this; closer to the limb, so it better shows the changing aspect due to Sun's rotation:

Thanks to Filip for another great animation and detailed answer. You did a great job, the animations are excellent! The latter seemed to me even more dynamic. :bow
