20101206 Sun

The sun is putting on a fine show today, we have a long filament, two big active regions, some very big (a bit dim) prominences.

I also had some visual observation with my Nagler 13mm, AR1131 is three dimensional! That large group of prominence is fantastic! You know, I can see layers of hydrogen in AR1131... you know, H-alpha solar observation is definitely addicting.
