Before I setup, clear skies, but when I was ready to start imaging, 85% cloud coverage. So today’s session was pretty frustrating.  As a result I was not able to get the darks I usually take.   At the beginning of the day, Solar Activity was Medium with two M-Class flares and 10 C-class flares in the last two days.  However, today the Sun has continued it activity and so far created 5 M1.x flares as well as one M5.5 flare, triggering an R2 alert.  AR2674 has grown to 940 millionths while the total Active Region Area for the Sun is 1140 millionths and the spot count is 46.  In addition, two nice prominences could be observed.
