Bulletin

Catania sunspot group 88 (NOAA AR 2192) remains very active and, since the previous bulletin, produced eight M-class flares and about ten C-class flares. The strongest was an M7.1, peaking at 00:34 UT today. For none of these flares an associated Earth-bound CME was observed. The region retains its area and magnetic complexity and is expected to produce additional flares up to the X-level. Due to it's current location, a major eruption from Catania group 88 may result in a rise of the proton flux. A long filament in the northern hemisphere is continuing its passage across the solar central meridian. Its possible eruption may lead to an Earth- directed CME. ACE observations indicate a slow solar wind, with a speed ranging between 350 and 450 km/s. The interplanetary magnetic field magnitude reaches values up to 8 nT. Mostly quiet geomagnetic conditions are observed and are expected to continue with potentially an isolated time slot of active (K=4) conditions.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 082, basierend auf 13 Stationen.
