Description

After a few days quiet period, I got up today and checked the GONG network and SDO and the sun was going crazy! No big sunspots, but all sorts of h-alpha activity. Here's a large prominence that's just rotated off the disk into profile view.

One of these days I need to try my hand at making an animation.
