Bulletin

Solar activity continues to be dominated by NOAA ARs 2235 (Catania 51) and 2239 (Catania 54). The strongest flare was an M1.9, from AR 2239 peaking at 11:49 UT on May 6. A filament eruption to the east of NOAA AR 2235 created a partial halo CME (with angular width around 140 degrees and speed of 300 km/s), first seen by LASCO-C2 at 19:00 UT on May 6. This CME is mostly directed to the south, but it may have an Earth directed component, expected to arrive on May 10.

Active conditions (K=4) were observed yesterday locally in Belgium and minor storms (Kp=5) at planetary levels. The Earth is still under the influence of the CME from May 2 with magnetic fields slightly above 10 nT. If Bz turns to the south active conditions may occur again.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 101, basierend auf 21 Stationen.
