Bulletin

Solar activity has been low to moderate in the past 24 hours. NOAA AR 2027 produced a C8.3 flare on April 4th, peaking at 13:48 UT. It was associated with a type II radio burst, an ejecta/filament seen in 304A data, an EUV coronal wave observed at 193A and a partial halo CME in LASCO C2. EUV and coronagraphic observations suggest that the bulk of the CME is going essentially northward, but the shock driven by the CME might arrive at Earth around April 8th, mid-day. We expect active conditions in the next 48 hours, with M flares possible in the vicinity of ARs 2027 and 2030 as well as in AR 2026. Geomagnetic conditions were very quiet in the last 24 hours. The latest ACE observations show a weak shock signature on April 5th, around 09:30 UT possibly associated with the CMEs of April 1st and April 2nd. There is currently a weak jump in Btot and speed, and a weak drop in temperature and density. We expect unsettled to active conditions in the coming hours, with a return to quiet conditions on April 6.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 107, basierend auf 10 Stationen.
