Bulletin

Solar activity was low with only a single C flare originating from Catania group 80 (NOAA region 2457) peaking at C1.6 level at 2:14UT. Some new flux emerge occurred in the leading part of Catania group 77 (NOAA 2454) while the other regions were fairly stable. The occurrence of further occasional C flaring is quite possible over the next period. No Earth directed CMEs were observed in available coronagraph images.

Solar wind speed was in the 370-430 km/s range with total magnetic field increasing to a peak of 9.6 nT in the first half of the period before restoring to values of around 5 nT. Bz was mostly positive with a dip down to -5 nT before midnight. Geomagnetic conditions were quiet (local K Dourbes 1-2) with only a period of unsettled conditions at planetary level (NOAA Kp 0-3). Nominal wind conditions and associated quiet geomagnetic conditions are expected to continue.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 056, gebaseerd op 11 stations.
