Bulletin

Solar flaring activity was low. Most low class C-flares originated from NOAA AR 2277 (Catania groups 78, 79), with the largest event a C3.3 flare peaking at 9:53UT. Also Catania 82 (NOAA 2280) produced a C3 flare peaking at 19:12UT. Growth was observed in Catania 82 (NOAA 2280) as well as opposite polarity flux emergence in Catania 79 (the trailing part of NOAA 2277). Flaring is expected to continue at C level with just a minor chance for an isolated C flare from NOAA AR 2277 (Catania groups 78, 79). Two filament eruptions are clearly visible in SDO AIA304. A filament located north of Catania 82 (NOAA 2280) lifted off at 19:23UT followed by an eruption of a filament located east of Catania 79 around 23:09UT. Preliminary coronagraphic data show the first event to have resulted in an associated narrow northeast directed CME. We await more coronagrahic data for a proper assessment, especially concerning the second event. Solar wind speed continued to decrease continuously from around 470 km/s to about 410 km/s. The total magnetic field was initially stable around 3.5 nT becoming variable in the 0 to 5 nT range since later this morning. The Bz component was variable with downward excursions near -5 nT. Geomagnetic conditions were quiet to unsettled (both NOAA Kp and local KDourbes 1-3). Further stabilisation at nominal solar wind conditions is expected with consequent quiet to unsettled geomagnetic condition.
