Bulletin

There are currently 7 sunspot groups visible. They are small and stable, except for NOAA 1996 and NOAA 2002 who gradually gained some sunspot area and developed a small delta in their middle portion. Most flaring activity came from NOAA 2002, with at least 7 C-class flares and one M1-flare peaking at 23:41UT, the strongest event of the period. Based on the currently available imagery, none of the observed CMEs has an Earth directed component. The CME first visible in LASCO/C2 at 18:24UT on 8 March seems to be related to a backside event (coronal dimming near an active region). Eruptive flaring conditions are expected, with a small chance for an M-class flare. Over the last 24 hours, solar wind speed has gradually decreased to values near 350km/s, with Bz varying between -3nT and +3nT. A small coronal hole on the southern hemisphere reached the central meridian (CM) and may have a geomagnetic influence on 12-13 March. Geomagnetic conditions have been quiet. The coronal hole solar wind stream (CM passage 5 March) has not arrived yet. A local active geomagnetic episode remains possible.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 083, basierend auf 16 Stationen.
