The Sun produced four C-class flares during the past 24 hours, the largest one being a C4.8 peaking at 3:57 UT. All flares originated from NOAA active region 2396. A new unnumbered region has turned to the visible side, which adds the total number of active regions up to six. No Earth- directed CMEs were observed. More flares at the C-level are expected.

Earth is under influence of a flow at moderate speed, emanating from an equatorial coronal hole. Solar wind speed reached values of maximally 650 km/s, but declined to current values near 500 km/s. The magnitude of the interplanetary magnetic field (IMF) obtained values in the range of 5 to 11 nT with mainly negative Bz. At 9 UT, this resulted in geomagnetic active (K=4) conditions at the local level (Dourbes) and even minor storm conditions at the planetary level (estimated NOAA Kp=5). A few further time slots of active to minor storm conditions are possible before returning to quiet to unsettled (K=0-3) levels.
