Bulletin

Solar X-ray flux remained below B level. The developing region mentioned already yesterday, now became numbered as NOAA 2760 and developed into a small bipolar region. Solar flaring is overall expected to remain below C level over the next days.

There were no Earth directed Coronal Mass Ejections (CMEs) observed in the available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels over the past 24 hours and is expected to stay at nominal levels. The greater than 2 MeV electron flux has remained just slightly enhanced over the past 24 hours.

Solar wind was in a close to nominal regime with Solar wind speed around 400 km/s and total magnetic field around 5nT. Bz was unremarkable and the magnetic field phi angle was stable in the negative sector. Nominal Solar wind conditions are expected over the next days.

Geomagnetic conditions were essentially quiet with some isolated unsettled episodes locally (local K Dourbes 0-3 while NOAA Kp 0-2). Quiet geomagnetic conditions are expected over the next days with isolated unsettled episodes possible.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 014, gebaseerd op 23 stations.
