The sun produced one M and three C flares during the past 24 hours. Catania sunspot region 29 (NOAA AR 11884) was responsible for the M6.3 flare peaking at 19:46 UT on November 1. Also Catania sunspot region 28 (NOAA AR 11885) produced a C8.2 flare with a peak at 4:46 UT on November 2. During the next 48 hours, more C flaring activity is expected with a slight chance for an M flare. Two CMEs of which one full halo CME were detected in coronographic imagery (LASCO/C2 as well as STEREO A and B), but first analysis indicates both are backsided and originate from old NOAA AR 11875. The full halo CME was first seen in LASCO/C2 at 5:00 UT and the second CME at 8:12 UT directed to the NW. Solar wind speed as observed by ACE is around 350 km/s. The magnitude of the interplanetary magnetic field (IMF) currently is stable near 5 nT. Geomagnetic activity is quiet to unsettled (local K at Dourbes and NOAA Kp between 0 and 3), which is expected to remain so within the next 48 hours.
Today's estimated international sunspot number (ISN): 069, based on 02 stations.
