Bülletään

The Sun produced four C-class flares since our last bulletin. A C4.7 flare, peaking at 1h52 UT on April 10, originated from the active region complex with the recurrent NOAA ARs 2019, 2010 and 2023 and is currently situated at the East limb. Also NOAA AR 2030 did produce a C1.2 flare peaking at 0h13 UT on April 10, which seems associated with a slow CME (first measurement in LASCO at 0h48 UT of April 10) that is propagating in westward direction. Further analysis is needed to determine whether this CME has an Earth-bound component. More C-class flares are expected especially from the active regions that are currently rotating around the East limb. Also an isolated M-class flare is possible during the next 48 hours. Normal solar wind parameter values are measured by ACE. The solar wind speed is currently near 420 km/s and the interplanetary magnetic field has a value of about 5nT. Current magnetic conditions are quiet to unsettled and are expected to remain so till the arrival of the CH high speed stream, which might result in active conditions from April 12 on.
