Two C-class flares were observed during the past few hours. A C1.4 flare at 7h57 UT originating from Catania sunspot group 82 (NOAA AR 1756) was a long duration event. This is associated with a rather small limb CME propagating to the South West and based on currently available information it is expected not to be Earth directed. A C1.1 flare at 11h27 UT was originating from Catania sunspot group 88 (NOAA AR 1761). C-class flaring activity is expected for the next 48 hours. The current solar wind speed is at 350 km/s. The interplanetary magnetic field has a magnitude of 5 nT with a mainly negative Bz-component. Geomagnetic conditions are still quiet (local K<3 at Dourbes). The geomagnetic index is expected to increase later today and tomorrow and reach active to minor storm levels (K=4 to 5), due to the effects of a fast speed stream.
