Bulletin

Alpha region NOAA AR 2703 has produced a few low B flares and a B9.0 flare in the past 24 hours. The chance for a C flare in the next 24 hours is estimated at 40%, mainly from AR 2703. No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to remain so. Solar wind speed as registered by DSCOVR varied between about 430 and 475 km/s, with current values around 440 km/s. The Interplanetary Magnetic Field (IMF) was below 5.3 nT. Bz component varied mainly between -3 and 3 nT being mainly positive. Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp between 1 and 2) were registered in the past 24 hours. Mostly quiet geomagnetic levels (K Dourbes < 3) are expected on April 2, 3 and 4.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 000, sur la base de 16 stations.
