公告

Solar activity was moderate with an M5.1 flare from NOAA AR 2173 peaking at 2:58 UT. It was associated with type II radio bursts and a dimming. Coronagraph data however seen to indicate just a narrow south- eastward directed CME. AR 2172 and 2173 produced a further number of C flares. AR 2172, 2173, and 2175 remain active and are the most likely sources on disc. New flaring activity at M level is likely. With the main active regions on disc approaching moving to the west the chances for a proton event are increasing. After touching minima of below 380 km/s in the first half of the reporting period, solar wind speed picked up slightly again to around 420 km/s presently. Total magnetic field was mainly in the 5-7 nT range with Bz variable mainly in the +-4nT range with a period of negative Bz peaking below -5nT around 10:00 UT. Geomagnetic conditions were accordingly quiet with unsettled conditions late this morning. Quiet to unsettled conditions are expected to continue with some active periods still possible in the first 24 hours.
