Loop prominence and AR3190 timelapse animation, 25th January

Hi everyone - been a long gap in posting, but here is a 48-frame, 50min timelapse of some really cool activity on the western limb of the Sun as the big spot region AR3190 departed last week. There's a lot going on in the scene - with plasma blobs running across the big loop at upper left; some small loops and plasma rain on the right; small flare-ish activity in AR3190 and 3194 (small active region at upper right); various other bits of activity around the regions, and even a tiny spiral puff from an otherwise quiet area 2/3 of the way through the sequence at about centre-left. I find myself still noticing new things in the sequence even after watching it many times. Hope you enjoy!

The animation is here

Equipment: Skywatcher Evostar 100, Quark CS, ZWO ASI174MM. 1 frame per minute, each frame is 15s exposure @~130fps, with the best 20% stacked and sharpened, the sequence combined in PS. Seeing was mostly fair, and excellent towards the end. I've attached a single frame from the sequence to give an immediate idea of the animation.
