Bulletin

Solar activity has been eruptive during the past 24 hours, featuring one C1.7 flare from NOAA AR 11834 peaking at 14:20 UT. More C flares from NOAA AR 11834 and 11836 are likely within the next 48 hours, with a slight chance for an M flare. Solar wind speed rose from about 460 to 580 km/s around 6h UT on September 1, possibly due to the effects of the CME of August 30. Solar wind speeds later decreased to about 430 km/s and climbed to a peak of 520 km/s around 3h UT on September 2. Current wind speed lies around 420 km/s. Meanwhile, the Interplanetary Magnetic Field varied between 2 and 6 nT. Solar wind may experience the influence of a small Coronal Hole on September 4. The geomagnetic activity was at quiet levels (K Dourbes between 1 and 3; NOAA Kp between 2 and 3) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for September 2 and 3. Quiet to active conditions are possible on September 4, due to the effects of a Coronal Hole high speed stream.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 058, gebaseerd op 11 stations.
