Bulletin

There are currently nine numbered sunspot groups on the solar disc, and three of them have beta configuration of the photospheric magnetic field. Three low C-class level flares were reported during last 24 hours and all originated from the same NOAA AR 1850, which just turned from behind the east solar limb. We expect more flaring activity at the C-class level. The M-class flares are possible but not very probable. The solar wind speed is about 480 km/s and slowly decreasing, and the interplanetary magnetic field magnitude is stable amounting about 3 nT. The geomagnetic conditions are at the moment quiet. We expect quiet to active geomagnetic conditions in the following 48 hours due to the arrival of a fast flow (in the morning of September 22), associated with the low-latitude coronal hole in the northern hemisphere.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 062, basierend auf 12 Stationen.
