Bulletin

NOAA 2222 has increased its sunspot area, but somewhat simplified its magnetic configuration, resulting in only 3 low-level C-class flares. To the southwest of this region, Catania 22 produced the strongest flare of the last 24 hours (C7.5 peaking at 00:40UT). The other sunspot regions were quiet, with NOAA 2219 still having some mixed polarities. The x-ray background flux has decreased to the C1 level. A filament eruption occurred between 04:45 and 05:45UT near and to the NW of NOAA 2222. The associated CME became first visible in LASCO/C2 at 05:48UT. It is not Earth-directed, like the other CMEs observed over the last 24 hours. C-class flaring is expected, with a chance on a low-level M-class flare. Solar wind speed gradually declined and varied between 400 and 350 km/s. The IMF is directed towards the Sun, with Bz mostly positive and varying between -10 and +10 nT. The geomagnetic field was quiet to unsettled (K<4) and is expected to remain so.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 104, basierend auf 10 Stationen.
