I had a nice, sunny Sunday with good-to-average seeing.

Best frames, showing active regions 2018 and 2020:

I started in the morning with the big prominence, it was calm enough back then (30 s intervals, 1:00 h total):

...but a few hours later (I think it was the same one - it appears this way in the GONG archive) it became a bit more lively (same speed, 1:04 h total):

A bit disappointing, I was counting on more pore movement, like in this animation from a few years back:



And finally — my first CaK animation (30 s intervals, 0:58 h total):

Interesting little sparks in the lower sunspot, but according to NOAA there were no flares there at the time.

Great job!
In the calcium line, everything is very dynamic.
Most of all, I liked the second animation with prominences.

Great set!!! You should try stopping the scope down to 60mm for the CaK, will sharpen these up considerably.
