The strongest flare reported, during last 24 hours was GOES M1.6 flare (peaked at 03:53 UT this morning). The impulsive flare originated from the presently most complex active region observed on the visible side of the solar disc, NOAA AR 3031, which still has beta-gamma configuration of its photospheric magnetic field. In the coming hours we can expect flaring activity at the C-class level, and also isolated M-class flares. During last 24 hours there were no Earth-directed CMEs reported. The NOAA AR 3031 is approaching to the West solar limb and large eruption from that active region could be associated with the particle event. During last 24 hours the greater than 10 MeV proton flux was at background levels, and the greater than 2 MeV electron flux was under the 1000 pfu threshold, we expect them to remain on these levels in the coming hours. The 24h electron fluence is at normal level and we expect it will stay so in the coming 24 hours.
The solar wind velocity is still somewhat elevated, and it presently amounts about 550 km/s and the interplanetary magnetic field is about 6 nT. The geomagnetic conditions are presently quiet to unsettled and we expect them to stay so in the coming hours.
