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.

Solar wind speed gradually increased from initial values around 360 km/s to near 400 km/s at the end of the period (ACE). The interplanetary magnetic field (phi angle) was predominantly directed towards the Sun (negative sector). Bz varied between -6 and +5 nT, with a sustained negative stretch near -5 nT between 19-22UT that resulted in unsettled to active geomagnetic conditions during the 21-24UT interval (Kp = 3; K Dourbes = 4). For the remainder of the period, geomagnetic activity was mostly at quiet levels.

Geomagnetic activity is expected to remain at mostly quiet levels, an unsettled interval not excluded.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 000, gebaseerd op 28 stations.
