Half-cloudy in the morning and I took the opportunity to look at the sun between the clouds. Quite turbulent atmosphere and a bit poor vision, but tried to photograph the entire solar disk with 5 images then stitched together in Photoshop. The first thing I noticed were all the filaments on the sun and a couple of nice prominences (now it's the same thing but from different angles).

A filament on the sun is a large, winding cloud of hot gas (plasma) that is held above the sun's surface by strong magnetic fields. Since the gas is slightly cooler than the surrounding sun's surface, they look like dark, thread-like structures when you photograph the sun straight ahead.

If the same phenomenon is seen from the side, at the edge of the sun, it is instead called a prominence and looks like a bright, reddish arc that extends into space.

You can see this at the bottom left of the sun where a filament disappears over the edge and a prominence becomes visible.

Otherwise, an active sun with areas of sunspots and a chance for solar storms.
