Bulletin

There are currently 6 sunspot groups visible on the solar disk. Eight low-level C-class flares and one M-class flare were observed during the period. The latter reached a maximum of M1.5 at 02:16UT, and originated in NOAA 2157. The CME associated to this event was first observed by LASCO at 03:12UT. It had a speed of about 350 km/s (CACTus), but has no Earth- directed component. NOAA 2157 and NOAA 2158 continue their decay. However, together with NOAA 2164, they have spots of opposite magnetic polarity close to each other. Hence, they may still produce an M-class flare. Filament eruptions observed around 16:30UT (northeast quadrant) and 20:00UT (south of NOAA 2163) were not related to earth-directed CMEs. M-class flares remain possible. Solar wind speed decreased from about 600 km/s to 500 km/s, while Bz decreased from +15 nT to a steady +6 nT. Geomagnetic conditions were quiet and are expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 070, basierend auf 10 Stationen.
