The sun on 02/07/2013

After missing a 10 hour flare yesterday (how could I have??!!), I almost didn't image today.  However, I am glad I did as there were some nice prominences visible as well as filaments and decaying active areas.  The focus isn't what I would like it to be on these images; I think I did not have the imager seated properly and the focal plane was tilted. The horseshoe-shaped area to the left of the large filament is AR 1667, which was actively flaring yesterday.
