Bulletin

Solar activity has been low in the past 24 hours, with only C class flares. One noticeable event, a C3.3 flare, took place in NOAA AR 2066 on May 17, 0229 UT (peak time). There is no clear signature of a CME associated with that event. Two wide CMEs were observed in the past 24 hours. The first one, on May 16, 1424 UT is associated with a backside flare. The second one, on May 17, 0125 UT, is associated with a filament eruption, also on the backside. We expect eruptive conditions in the next 48 hours, with risks of C flares from NOAA ARs 2063 and 2066. Geomagnetic activity has been very low in the past 24 hours. We expect quiet conditions to prevail for the next 48 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 107, gebaseerd op 17 stations.
