The solar flaring activity is low, with only low C-class flares and B-class flares reported in the last 24 hours. Out of eight numbered active regions, situated on the visible side of the Sun as seen from Earth, the most complex region is NOAA AR 3031 (Catania sunspot groups 44). This active region remains to have beta-gamma configuration of its photospheric magnetic field and it is possible source of flaring activity. In the coming hours we can expect C-class flares while isolated M-class flares are possible but not very probable. The observations do not show the Earth-directed CMEs during last 72 hours.

The NOAA AR 3031 is approaching to the West solar limb and the strong flares and larger eruptions from that active region can be possibly associated with the particle event. 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, and 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 high with the present value of about 590 km/s. The interplanetary magnetic field magnitude remains to be 6 nT. The geomagnetic conditions are presently unsettled to quiet and we expect them to stay so in the coming hours.
