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 370 km/s to near 320 km/s by the end of the period (ACE). The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector), with some short intervals in the positive sector. Bz varied between -3 and +3 nT.

Geomagnetic activity was quiet, with the Kp index (NOAA) and the local k index (Dourbes) recording values of 0-2. Quiet conditions are expected to continue, with possible unsettled intervals on December 3 and 4, due to the influence of a small extension from the southern polar coronal hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 18 stations.
