A few new regions developed themselves during the past period. NOAA active regions (AR) 2287, 2288 and 2290 are the most interesting ones. NOAA ARs 2287 and 2288 evolved to beta regions, while NOAA ARs 2286, 2289, 2290 are alpha regions. Flaring activity slightly increased with three C-class flares. The strongest flare was a C3.5 flare, originating from the northern part of NOAA AR 2282. More C-class flares are expected, mainly from NOAA 2282, 2287, 2288 and 2290. No Earth-bound CMEs were observed. The solar wind was at nominal levels, with the magnitude of the interplanetary magnetic field between 3 and 5 nT and a fluctuating Bz component. The solar wind speed slightly decreased from 470 to about 400 km/s. Geomagnetic conditions were quiet to unsettled (K=1 to 3), at the global and local level (Dourbes), which is expected to continue for the next 48 hours.
