The GOES X-ray background radiation is at the C-level. Several C-class flares were observed during the past 24h, mainly in NOAA AR 1909 and in the returning regions on the east limb. We expect more C-flares, especially from these east limb regions, with a small chance for an M-class flare. A large scale filament eruption was observed on December 04, starting from 11:00 UT. This resulted in a slow CME, mainly oriented towards the north. Another filament erupted in AR 1909 around 21 UT on December 5th. While there is a gap in LASCO data, COR2-A images clearly show the associated slow CME. The activity on the east limb also resulted in several CMEs towards the SE (as seen from LASCO). We expect unsettled to active conditions (up to K=4) on December 7 due to the arrival of a coronal hole high speed wind stream. This coronal hole, which seems to have increased in size in the last 24h, passed the central
meridian on December 4. Afterwards, geomagnetic conditions should return to quiet conditions until December 9th when Earth may feel the influence from the ICME associated with the filament eruption in AR 1909. A glancing blow from the east limb CMEs is also possible.
