During last 24 hours several C-class and one M-class flare were reported. The GOES M3.0 flare (peaked at 05:53 UT) was reported this morning. The flare originated from the region situated at the East solar limb, presently rotating to the visible side of the solar disc. The NOAA AR 3270 is still the most complex active region observed on the visible side of the solar disc, presently having beta-gamma configuration of its photospheric magnetic field. In the coming hours we can expect the C-class flares, the isolated M-class flares are possible but not very probable. The CME associated with the M3.0 flare had angular width of about 50 deg and velocity of about 450 km/s. We do not expect that this narrow and slow CME will arrive to Earth. The greater than 10 MeV proton flux remained at the background levels, and the greater than 2 MeV electron flux was fluctuating around the 1000 pfu threshold. The 24h electron fluence is still at moderate to normal level. We do not expect significant change in these three parameters in the coming 24 hours.

The solar wind velocity strongly decreased during last 24 hours and its present value is about 400 km/s. The interplanetary magnetic field magnitude is around 5 nT. During last 24 hours the geomagnetic conditions were quiet and we expect such a geomagnetic conditions to persist in the coming hours.
