Bulletin

The sun produced one M and seven C flares during the past 24 hours. Catania sunspot region 18 (NOAA AR 11877) was responsible for the M1.9 flare peaking at 13:51 UT on October 31. Most C flares originated from Catania sunspot region 29 (NOAA AR 11884). During the next 48 hours, more C flaring activity is expected with a slight chance for an M flare, especially from Catania sunspot region 29 (NOAA AR 11884), which retains a beta-gamma-delta configuration of its photospheric magnetic field. LASCO/C2 (at 18:12 UT on October 31) and LASCO/C3 observed a mainly south directed CME, which will at most only produce a glancing blow. Due to the low speed (CACTus estimation 254 km/s), no effect on geomagnetic conditions is expected. Solar wind parameters observed by ACE indicated the arrival of a weak transient at 10:00 UTC on October 31, possibly related to the CME of 15:24 UT on October 28. A slight increase in solar wind speed, temperature and density was measured. The magnitude of the interplanetary magnetic field (IMF) went to 12 nT and is now stable around 5 nT. Current solar wind speed is around 350 km/s. 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.
