Bulletin

Solar activity continues at the C-class flaring level. Returning NOAA AR 2088 (no Catania number) produced a C3.4 flare with peak at 07:44 UT. More C-class and probably M- class flares can occur as this region and NOAA AR 2082 (no Catania number) rotate today into the visible solar disk. Geomagnetic conditions are quiet. The arrival of a fast solar wind stream today will increase conditions to unsettled to active levels.

Today's estimated international sunspot number (ISN): 043, based on 13 stations.
