Bülletään

Five sunspot regions are visible at the front side of the solar disk. Catania sunspot group 34 (NOAA AR 2049) showed some growth. All other groups were stable. One C3.4 flare was measured by GOES (peak time 15:26 UT on 28 April), originating from Catania sunspot group 31 (NOAA AR 2048). More C-class flares are possible during the next 48 hours. No Earth- directed CMEs were observed. Solar wind speed has declined to only 280 km/s. The magnitude of the interplanetary magnetic field is currently lower than 5 nT. Geomagnetic conditions were quiet and are expected to remain as such. An isolated time slot of active conditions is still possible at arrival of a high speed stream related to the coronal hole that passed the central meridian early on 24 April.
