Medium activity today on the Sun  with 10 Active Regions, and 69 spots covering 910 millionths. 10 C-class flares were reported in the last 24 hours.  AR2339, although decaying, is still big at 670 and its 51 sunspots only created 2 flares.  The new firecracker is probably going to be 2345 which showed today 4 C-class flares of which one was a C-9.2.  A very nice prominence showed at the NE limb, 53,000 miles high and 152,000 miles wide as seen from Earth.
