Bulletin

Eight C-flares were observed during the past 24 hours, all originating from Catania sunspot region 87 (NOAA AR 1928). NOAA AR 1934 (no Catania number yet) shows some growth. There were no Earth-directed CME observed. The probability for C-flares is around 70% and for M-flares around 30%, from NOAA ARs 1928, 1930 and 1934. An X-flare is possible but unlikely. We are currently in a slow solar wind stream with a solar wind speed of 350 km/s and a magnitude of the interplanetary magnetic field of maximally 6 nT (observed by ACE). Current geomagnetic conditions are quiet to unsettled (Kp<4) and are expected to remain so during the next 48 hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 097, gebaseerd op 04 stations.
