Bulletin

Catania sunspot groups 78 (NOAA AR 1665) and 79 (NOAA AR 1667) produce small flares, hardly reaching the C-level. Although, an isolated C-flare is possible. The Earth undergoes a limited influence of the small equatorial coronal hole: the local K indicating the geomagnetic disturbances measured in Dourbes, Belgium became 3. The solar wind heading for Earth has become faster: >400km/s. The temperature of the solar wind particles has increased accordingly. The magnetic field is stronger compared with the first part of Feb 01. A large coronal hole in the northern hemisphere, although at a high latitude reached the central meridian. Geomagnetic influence is possible in a few days. There is a small probability for a glancing blow of the filament that erupted on Jan 31, 06:00UT. In case of arrival, unsettled to active conditions are possible.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 049, basierend auf 09 Stationen.
