Bulletin

Solar activity was at very low levels. The Sun was spotless once again. 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.

Solar wind speed evolved in a generally declining trend, from about 400 km/s at the beginning to 330 km/s at the end of the period (ACE). Bz varied between -4 and +3 nT. Solar wind parameters reflected a Sector Boundary Crossing (SBC) around 05:30UTC, with the direction of the interplanetary magnetic field (phi angle) switching from mostly directed away from the Sun (positive sector) to predominantly towards the Sun (negative sector). Geomagnetic activity was at quiet levels (both Kp and K Dourbes).

Geomagnetic activity is expected to remain at quiet levels, with a chance on an unsettled interval.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 06 stations.
