Coronal Loops are Nice to Look At!

As Solar Cycle 25 starts becoming more active, coronal loops have become more common and beautiful. Here is a movie from June 24, 2021, showing the decaying remnants of AR 12833 rotating off the Sun in the upper right and the just-forming AR 12835 rotating into view in the lower left. You can see small filaments in and around the two active regions, with a very nice filament liftoff in the area following AR 12833.
There are many filaments visible around the limb of the Sun. In the lower left, around 7:30, you can see what looks like a coronal cavity (a filament surrounded by a dark, more-or-less circular, region.
Solar Cycle 25 is looking good!
