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:

My software:
Stackistry — an open-source cross-platform image stacker
ImPPG — stack post-processing and animation alignment

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