Bulletin

Solar activity again was very low with four lower C-class flares (C1.7 as maximum), originating from NOAA active regions (AR) 2494 and 2496. NOAA ARs 2495 and 2497 have clearly grown in number of spots, while NOAA 2492 has also shown some development in its leading and intermediate part. NOAA AR 2494 is further decaying especially in its leading area. All other regions remained largely simple. Flaring activity is expected at C-level, with a slight chance for an M-class flare. No new Earth-directed CMEs were observed.

The solar wind conditions were normal with magnitude of interplanetary magnetic field (IMF) maximally 6 nT and solar wind speed between 400 and 450 km/s.

Geomagnetic conditions were quiet (K=1-2) to unsettled (K=3), both at the local (Dourbes) and global level (NOAA estimate), which are expected to continue till the possible arrival of an Earth-directed component of the February 5 CME on February 9.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 095, gebaseerd op 13 stations.
