Bulletin

NOAA AR 1907 was responsible for the several B-flares and the 1 C-flare on November 30. We expect that the flaring situation stays as it is: a chance of 50% for C-flares, 20% for an isolated M-flare and almost zero chance for X-flares. A partial halo CME was detected on November 30 coming into the field of view of SOHO/LASCO C2 around 14:00 UT in the SE. No on disk signature could be linked to this event. STEREO B EUI 195 indicates some flaring activity and a mass ejection around that time from a region near the centre of the STEREO B solar images. This CME is determined as back-sided. The solar wind speed has reached 500 km/s since late November 30. The z-component of the interplanetary magnetic field (IMF) was mainly negative resulting in a planetary and local (Dourbes) K-index of 4 late November 30. We expect the solar wind speed to decrease gradually. We expect quiet geomagnetic conditions with possible unsettled conditions (K=3) for the remaining part of December 1.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 084, basierend auf 15 Stationen.
