Bulletin

Solar activity has been eruptive during the past 24 hours, with two C flares produced by NOAA AR 11708, the brightest one being a C2.7 flare peaking around 09:43 UT on April 3. More C flares are expected within the next 48 hours, with a slight chance for an M flare, especially from NOAA AR 11708 in which flux and sunspots are currently emerging. Geomagnetic activity was at quiet levels (K Dourbes between 0 and 3; NOAA Kp between 0 and 2) during the past 24 hours. Quiet (K Dourbes < 4) to active (K Dourbes = 4) conditions are predicted for April 3 to 5 due to an expected gradual rise in solar wind speed as a result of a coronal hole high-speed stream passing by.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 068, gebaseerd op 13 stations.
