公告

The strongest event of the period was a C4 flare peaking at 13:37UT being produced by NOAA 2290 from behind the NW limb. NOAA 2292 lost its delta, but still has some mixed polarities. The region produced 2 low- level C-class flares. An active region that has been the source of some strong CMEs over the last few days will round the SE limb within the next 1-2 days. No Earth-directed CMEs were observed. C-class flaring is expected. Geomagnetic conditions ranged from quiet to unsettled, with locally (Dourbes) an active episode at the end of the period. Earth has left the high speed stream from the southern polar CH. Solar wind speed gradually decreased from about 500 km/s to a steady 450 km/s after 22:00UT. Since 08:00UT, IMF direction seems to have changed from towards to away, and Bz started to oscillate between -8 and +8 nT. This may be in response to an anticipated sector boundary crossing. A positive CH is transiting the CM and may influence the geomagnetic field around 7 March. Quiet to active geomagnetic conditions are expected.
