Bulletin

NOAA AR 1909 produced an M1.2-flare peaking at 07:29UT. A plasma eruption was seen in this neighbourhood on December 5 around 21UT. An unstable filament in the neighbourhood of an active region is a recipe of disaster. The curve for the background X-ray radiation is situated near the top/bottom of the B/C level. The chances for more M-flares are around 30%. The fast stream linked with the coronal hole that approached the central meridian on December 3 might arrive late today and introduce unsettled/active conditions: K=3 up to 4. The filament eruption on December 5, around 21UT might have a glancing blow. There is no data of SOHO/LASCO at that time. The amount of available STEREO A data is also limited. A first estimate gives a speed of around 500 km/s. The shock might arrive late on December 9.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 062, basierend auf 09 Stationen.
