Bulletin

Solar activity was moderate in the past 24 hours, with only a C1.2 flare occurring in NOAA AR 1769, on June 14, 00:31 UT peak time. It was accompanied by a narrow, non-geoffective CME. Additional C flares are possible from this region. AR 1768 grew in size and complexity and is likely to produce C flares as well in the next 48 hours, with even a small risk for an isolated M class event. Therefore, we expect eruptive conditions for the next 48 hours. Geomagnetic conditions are currently very quiet, and we expect this situation to persist for the next 48 hours.

Today's estimated international sunspot number (ISN): 042, based on 11 stations.
