Bulletin

2 M-flares and 5 C-class flares were observed over the last 24 hours. The bulk of the flares, including the 2 M1-flares peaking resp. at 01:22UT and 02:11UT, originated from a region behind the southeast limb. The strongest C-class flare was a C6 that peaked at 08:23UT in a group just behind the northeast limb. Both regions are the return of the old regions NOAA 1944/1946. In particular NOAA 1944 was very active at that time with numerous M- and 1 X-class flare. Both regions remained very active during their backside transit. The two sunspot regions that are currently dominating the solar disk, NOAA 1959 and 1960, have been quiet. Further C-class flaring is expected with a chance on more M-class flaring. None of the observed CMEs are Earth directed. They are backside events, including an impressive CME first seen by STEREO-B/EUVI-COR2 imagery at 22:40UT. Solar wind speed was around 360 km/s, and Bz varied between -4 and +4nT. Geomagnetic conditions were quiet. Quiet to unsettled geomagnetic conditions are expected over the next 3 days.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 054, basierend auf 10 Stationen.
