Bülletään

In total 8 C flares occurred during the past 24 hours. A C6.5 and C6.0 flare were the strongest events. Both erupted from Catania sunspot group 98 (NOAA AR 1944). Also Catania sunspot group 9 (NOAA AR 1950) was responsible for two C flares. More C flares are expected within the next 48 hours with a chance of 90%. Chances for M flares are estimated at 40% and for X flares at 10%. We issue a warning condition for a proton event, due to position of NOAA AR 1944 which is rotating towards the west limb. No geo-effective CMEs were observed. The solar wind, measured by ACE, showed signatures of the arrival of the coronal hole high speed stream. Solar wind speed increased from about 400 km/s to 500 km/s. The magnitude of the interplanetary magnetic field reached a maximum of 9 nT and the Bz component varied between +8 and -8 nT. Geomagnetic conditions were quiet to unsettled. Quiet to active conditions are expected during the next 24 hours.
