Four C-class flares were observed originating from Catania sunspot region 24 (NOAA AR 2035), the largest one being a C5.3 peaking at 15:01 UT, April 11. The C5.3 flare was associated with an Eastward directed CME (first measurement of LASCO/C2 at 14:48 UT) with angular width of about 100 degrees and speed of 568 km/s as estimated by CACTus. At most a shock could arrive at Earth around 12h UT on April 14. More C-class flares are expected during the next 48 hours, especially from Catania sunspot region 24. Also an isolated M-class flare is possible. ACE observed an increase in the magnitude of the IMF from 7 to 11 nT, with a negative Bz currently reaching -9 nT. This resulted in active to minor storm magnitude conditions during the first half the UT day (local K=4 at Dourbes and even NOAA Kp=5). Solar wind speed has gradually declined to 350 km/s. Unsettled to maximally major storm conditions are expected due to currently negative Bz and the arrival of the CH high speed stream.
