Bülletään

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.
