Bulletin

The flaring activity during last 24 hours was on the low C-class level. The strongest flare reported was the C 3.0 flare (peaking at 17:07 UT on October 06), originating from the Catania sunspot group 69 (NOAA AR 2185) at that moment situated close to the east solar limb. The flare was accompanied with the coronal dimming and the CME first seen in the SOHO LASCO C2 field of view at 17:12 UT. The CME had angular width of about 110 degrees and the projected speed of about 350 km/s (as reported by CACTUS software package). This CME will not arrive at the Earth. We expect flaring of the C-class level in the coming hours. The Earth is currently inside a slow solar wind with the speed of 350 km/s. The interplanetary magnetic field is stable with the magnitude of about 4 nT. The geomagnetic conditions are quiet and expect to remain so during the following hours.

Today's estimated international sunspot number (ISN): 051, based on 16 stations.
