Bulletin

NOAA AR 1686 (S12W52) produced an isolated M1.2 flare peaking at 07:54 UT, C-class level activity can be expected for the coming hours. Dimmings associated with this flare suggest the presence of a CME, but there is nothing visible in STEREO-A and no LASCO data yet. STEREO-B witnessed a full halo CME starting at 04:10 UT (COR2), this is a backsided event not expected to arrive to the Earth. A filament erupted south-east of NOAA AR 1688 (S15E31) at 23:00 UT on March 4 leading to a narrow CME seen by STEREO-B, this event is not believed to be Earth directed, even though there is no LASCO data yet to confirm (data gap). Geomagnetic conditions have been quiet and are expected to remain so until the arrival of a fast speed stream in 24h that may lead to active levels.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 059, basierend auf 16 Stationen.
