Bulletin

Solar activity is low. The strongest flare reported during last 24 hours was the C1.5 flare with the peak time at 16:56 UT, on October 05. The flare originated from the Catania sunspot group 63 (NOAA AR 2177) currently situated close to the west solar limb. No Earth-directed CMEs were observed during last 24 hours. We expect C-class flares. An isolated M-class flare from the Catania sunspot group 64 (NOAA AR 2181) which has beta-gamma configuration of its photospheric magnetic field, is possible but not very probable. The solar wind speed is currently 400 km/s and the interplanetary magnetic field magnitude is about 4nT. The geomagnetic conditions are quiet and expected to remain so in the following 48 hours.

Today's estimated international sunspot number (ISN): 050, based on 09 stations.
