Bulletin

Solar activity was at low levels. NOAA AR 2712 (McIntosh: Cao; Mag.Type: Beta) produced several B-class flares. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10 MeV proton flux was at nominal levels. Solar activity is expected to be at low levels with some chance for C class flares. Solar wind parameters variations are very low. Solar wind speed was below 350 km/s. The total magnetic field was below 5 nT. The Bz component fluctuated between -3.5 nT and +3 nT. Geomagnetic conditions ranged between Kp index 1-2 (NOAA) and local K index 1-3 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet today. Unsettled geomagnetic conditions can be expected from tomorrow due to the influence of a positive polarity low lattitude extension of the northern coronal hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 031, gebaseerd op 22 stations.
