Bulletin

In the last 18 hours solar activity decreased and the last C-class flare was C1.8 flare which peaked at 13:26 UT on January 21. The Catania sunspot group 81 (NOAA AR 2628), which was source of the majority of the flaring in the last 48 hours has presently beta-gamma configuration of its photospheric magnetic field and could be the source of the C-class flares, and possibly but not very probably also source of an isolated M-class flare. No Earth directed CMEs were observed during last 24 hours.

The solar wind speed remains to fluctuate around 500 km/s, and the interplanetary magnetic field magnitude is about 5nT. The geomagnetic conditions are quiet to unsettled and we expect them to remain so in the coming hours.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 071, gebaseerd op 18 stations.
