Bulletin

Solar activity has been eruptive during the past 24 hours, featuring a C2.0 and a C3.0 flare, both from NOAA AR 11775. More C flares are probable within the next 48 hours, with a slight chance for an M flare. A filament eruption took place near 30N 15-45E on June 24, around 23h UT. This material is not expected to travel to Earth. The solar wind is still in a coronal hole high speed stream regime, with solar wind speeds ranging between about 500 km/s and 570 km/s, while the IMF decreased from 6 to 4 nT. Solar wind speeds are expected to remain high, but continue their gradual decrease on June 25 and 26. Geomagnetic activity was at quiet to active levels (K Dourbes between 1 and 4; NOAA Kp between 2 and 4) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for June 25 to 27.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 050, gebaseerd op 11 stations.
