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 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 decreased from around 340 km/s to near 300 km/s by the end of the period (ACE). The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector) for the first part of the period but switched to the positive sector from 3 UT. Bz varied between -3 and +5 nT.

Geomagnetic activity was quiet, with the Kp index (NOAA) registering 0 for the whole period and the local k index (Dourbes) recording values of 0-1. Quiet conditions are expected to continue, with a small possibility of an isolated unsettled interval on December 4, due to the influence of the extension from the southern polar coronal hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 17 stations.
