Bulletin

Solar activity was at low levels. The largest flare B9.8 originated at NOAA AR 2710 (McIntosh: Axx; Mag.Type: Alpha) peaked yesterday (24-May-2018) at 12:30 UT. 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 probability for C flares and minor chance for M flares. Solar wind parameters returned to the background fluctuations level. The solar wind speed gradually decreased from 500 km/s till about 380 km/s. The total magnetic field was below 5 nT. The Bz component fluctuated around 0nT between -2.5 and +2.5 nT. Geomagnetic conditions ranged between Kp index 0-2 (NOAA) and local K index 0-2 (Dourbes) over the past 24 hours. Geomagnetic conditions are expected to be quiet.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 033, gebaseerd op 20 stations.
