Bulletin

Solar activity has been eruptive during the past 24 hours, featuring nine C flares. The brightest flare (C3.6) peaked at 04:28 UT on September 4 and was produced by NOAA AR 11837 like most C flares in this period. More C flares are likely within the next 48 hours, with a slight chance for an M flare, especially from NOAA AR 11837. The solar wind speed ranged between 380 and 480 km/s in the past 24 hours. In the same period, the Interplanetary Magnetic Field decreased from around 8 to 4 nT. The geomagnetic activity was at quiet levels (K Dourbes between 1 and 3; NOAA Kp between 1 and 3) during the past 24 hours. Quiet conditions (K Dourbes < 4) are expected for September 4 to 6, with a chance for active periods on September 5, due to the effects of a Coronal Hole high speed stream.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 052, gebaseerd op 14 stations.
