Solar activity was moderate with NOAA AR 2277 (Catania 78, 79) producing an M1.2 flare peaking at 02:15UT. Apart from that, only some minor C flares were detected, mostly from NOAA 2277 (Catania 78, 79), but also from Catania 82 (NOAA 2280). NOAA region 2277 continues to carry opposite polarity field is its intermediate region. A new region rotated onto disc in the northern hemisphere and is numbered NOAA 2281. We expect C flaring for the coming days, especially from NOAA region 2277 with also a chance for an M flare. There is a slight chance for a proton event should 2277 produce significant flaring. A filament eruption occurred at 10N35E at 12:00 UT February 3. The associated CME was directed northeast and narrow. SoHA LASCO C2 showed two westbound CME's respectively souhwest from 3:12 UT onwards and northwest from 5:24 onwards. Both are judged to be originating from on or behind the west limb. No Earth directed CMEs were recorded. Solar wind conditions have been recovering from the influence of a high speed stream. solar wind speed has dropped continuously from around 580 km/s to about 470 km/s. Total magnetic field was roughly in the 2.5 to 4 nT range. with Bz variable but predominantly negative. The geomagnetic conditions were quiet to unsettled (NOAA Kp and local K Dourbes 2-3). A further decrease to nominal solar wind conditions is expected with associated and quiet to unsettled geomagnetic conditions over the next days.
