Bulletin

Solar activity was at very low levels. The visible solar disk was spotless. No earth-directed coronal mass ejections (CMEs) have been observed in the available coronagraphic 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 speed fluctuated between from 330 km/s to 400 km/s (ACE). The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector). Bz varied between -5 and +4 nT.

Geomagnetic activity was quiet, with the Kp index (NOAA) and the local k index (Dourbes) recording values of between 0-1 and 0-2, respectively. Quiet conditions are expected on Dec 7 with possible unsettled conditions from Dec 8, due to the influence from the weak, patchy negative polarity coronal hole that traversed the central meridian on Dec 5.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 08 stations.
