Bulletin

Several C-class flares and one M-class flare were observed during the past period. Flaring activity mainly originated from NOAA active region 2249 (no Catania number yet). The strongest was an M2.3 flare peaking at 2:16 UT on December 27. No Earth-directed CMEs were observed. More C-flares are expected, with a light chance for an isolated M-class flare. The solar wind speed was fluctuating in the range between 350 and 560 km/s with current values near 450 km/s. The magnitude of the interplanetary magnetic field was around 10 nT for the first half of the period and decreased later on to 5 nT. Geomagnetic activity reached active levels (K=4) at local (at Dourbes) and global levels (NOAA estimated Kp). Quiet to unsettled geomagnetic conditions are expected, with some chance for active conditions. TODAY'S ESTIMATED ISN : ///, BASED ON /// STATIONS.
