Bulletin

There are currently eight numbered sunspot groups on the solar disc, and the most complex one is the Catania sunspot group 98 (NOAA AR 1944). The flaring activity, during last 24 hours, was at the B-class level. The last C-class flare reported was C3.9 flare which peaked at 02:06 UT, on January 12. The flare originated from the Catania sunspot group 98 (NOAA AR 1944) which continues to decay, but remains classified as a beta- gamma sunspot group. We expect C-class flares and possibly but not very probably M-class flare. Catania sunspot group 98 (NOAA AR 1944) is at the moment close to the west solar limb, therefore, we maintain the warning condition for a proton event. The Earth is currently inside a fast solar wind (800 km/s), associated with the extended (in latitude and in longitude) coronal hole in the northern hemisphere which first reached the central meridian on January 8. The interplanetary magnetic field magnitude is about 7 nT. We expect quiet to unsettled geomagnetic conditions in the next 24 hours.

Estimation du nombre international de taches solaires (ISN) pour aujourd'hui : 095, sur la base de 16 stations.
