Bülletään

The increase of the solar activity in the last 24 hours was mainly due to flaring from the Catania sunspot group 81 (NOAA AR 2628) which produced 9 B-class and 5 C-class flares. The Catania sunspot group 80 (NOAA AR 2627) also produced several B-class flares. The strongest reported flare was compact and confined C9.3 flare originating from the Catania sunspot group 81 (NOAA AR 2628), which peaked at 07:14 UT on January 21. In the coming hours we can expect B-class and C-class flares, in particular from the Catania sunspot group 81 (NOAA AR 2628). No Earth directed CMEs were observed during last 24 hours.

The solar wind speed amounts 480 km/s, and the interplanetary magnetic field magnitude is about 5nT. Presently, the geomagnetic conditions are quiet to unsettled and we expect them to remain so in the coming hours.
