Bulletin

Only C-1 class flares were observed since our last bulletin, originating in NOAA AR 12010 and 12015. The latter region reduced to a beta configuration and it is turning over the west limb. More C-class flares can be expected from NOAA regions 12010 and 12014, with a small chance for an M-flare. The warning conditions for proton events is maintained as the most prominent active regions are currently in the western hemisphere. The effects of the CME observed on March 23 are subsiding. Geomagnetic conditions were quiet (K and Kp <= 2) in the past 24h and are expected to remain so.

Today's estimated international sunspot number (ISN): 082, based on 14 stations.
