Description

Sun in H-alpha.

Animation of two hours of interval, from 14:43 to 16:41 UT. 21 frames, 60 seconds each, 3 minutes spacing.

Very variable seeing and cloud cover, as can be seen in the weird deformations of the solar disc.

Very few prominences, and sunspots, but lots of filaments and a very active AR 12291. It has put off a little C2.2 class flare, just before my imaging session (peak at 13:42 UTC), according to NOAA.

Mighty star.
