Solar activity is rather low with only one C-class flare reported in the last 24 hours. The C3.0 flare (peaked at 07:49 UT today), originated from the Catania sunspot group 55 (NOAA AR 2680), and was associated with the shock wave (type II radio burst was reported by HUMAIN station). Altgouh coronagraph data are not yet available, the presence of the on-disc CME signatures, EIT wave and coronal dimming, indicate that the flare was associated with the CME. More will be reported when coronagraph data become available. We expect isolated C-class flares in the coming hours. The particle event, associated with the X8.2 flare is still on going, but the level of the proton fluxes is slowly decreasing, and presently only fluxes with >10 MeV, > 50 MeV are above the event threshold. The Earth is presently inside the slow solar wind with the speed of about 460 km/s and the interplanetary magnetic field magnitude is about 4 nT. The CME-driven shock wave, associated with the X8.2 flare reported on September 10, still might arrive at the Earth in the coming hours. The fast solar wind, associated with the low latitude coronal hole in the northern hemisphere which reached the central meridian on September 10, is expected to arrive at the Earth in the mid-day tomorrow, September 13. We expect unsettled to active conditions within next 24 hours due to arrival of the CME-driven shock wave and the fast solar wind.
