Bulletin

Solar activity has been rather low in the past 24 hours, with C flares observed in NOAA ARs 1778 and 1780. The strongest event, a C2.7, took place in NOAA AR 1780, on June 30, 1517 UT (peak time). C flares are still possible from this region in the next 48 hours, and we therefore expect eruptive conditions over that period. A faint wide CME is observed on June 30, around 0400UT, but it seems to be a backside event. We expect unsettled to active conditions in the next 24 hours, due to the possible arrival of the CME of June 28, and then quiet conditions for the rest of the period. Current geomagnetic activity is quiet.

Today's estimated international sunspot number (ISN): 044, based on 10 stations.
