Its been 5 days since the last session.  AR2381 is the dominant active region today and pretty active. Today the sun shows medium flare activity with 15- C-class flares and two M-class flares and yes, all coming from AR2381.  The six regions contain 38 spots with a total of 630 millionths.  AR2381  itself is responsible for 350 of them, and has increased by 250 during the last day, adding to the chance for some more flares.  Today a  full disk in H-a as well as WL/Continuum and close ups of AR2381 with the same filters.
