Strongest flare reported in the last 24 hours was the X8.2 flare which peaked at 16:06 UT, on September 10. This long duration flare, originated from the Catania sunspot group 46 (NOAA AR 2673) which was, at the moment of eruption, already partially behind the west solar limb. The flare was associated with the EIT wave, halo CME and the shock wave which had projected speed of about 2900 km/s. The steep increase of the proton fluxes, with >10 MeV, > 50 MeV as well as >100MeV, associated with the X8.2 flare was observed yesterday. The proton flux levels are slowly decreasing, but they are presently still above the event threshold.The recently arrived data indicate that the arrival of the CME-driven shock wave, associated with the X-class flare, might be expected tomorrow morning (probably around 08:00 UT). The Catania sunspot group 46 (NOAA AR 2673), which was the source of the majority of the flaring activity during last few days, has rotated behind the west solar limb. Therefore, we expect solar activity to be low, with at most C-class flares.

The solar wind speed remains to be rather high, amounting about 600 km/s, and the interplanetary magnetic field magnitude is about 4 nT. The fast solar wind, associated with the low latitude coronal hole in the northern hemisphere which reached the central meridian in the mid-day yesterday, is expecting to arrive at the Earth on September 13. Geomagnetic conditions are presently quiet to unsettled. We expect active conditions within next 24 hours due to arrival of the CME-driven shock wave.
