Bulletin

Solar activity was at very low levels. The Sun remains spotless and no significant flares have been recorded. No Earth directed coronal mass ejections (CMEs) were observed over the last 24 hours in the available coronagraph imagery. The greater than 10 MeV proton flux was at nominal values. Solar activity is expected to remain at very low levels.

The solar wind fluctuated between 330 and 400 km/s (DSCOVR). Bz varied between -5.5 and +8.5 nT. The interplanetary magnetic field was predominantly directed towards the Sun (negative sector). Quiet to unsettled geomagnetic conditions were observed with the Kp index (NOAA) ranging between 1-2 and the local K index (Dourbes) ranging between 2-3.

Quiet to unsettled geomagnetic conditions are expected due to the continued influence of the solar wind streams associated with a series of fragmented negative polarity coronal holes.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 23 stations.
