It’s a Loopy Sun
This video covers January 5 through 7 and shows the 171 angstroms channel, which is especially good at showing coronal loops – the arcs extending off of the Sun where plasma moves along the magnetic field lines.
The brightest spots seen here are locations where the magnetic field near the surface is exceptionally strong. The characteristic temperature here is 1 million K (or 1.8 million F).
Many of these loops could fit several Earths inside of them.
