Bulletin

GOES Xray has observed several C-class flares since our last bulletin. They mainly originated from Catania sunspot groups 36 and 37 (NOAA AR 2051 and 2052). Catania sunspot group 36 has grown significantly and now has a beta-gamma-delta magnetic configuration of its photospheric field. The largest flare was a C5.3 flare from Catania sunspot group 36, peaking at 6:08 UT on 3 May. A small CME can be associated with this flare, travelling westward. The current SOHO/COR2 imagery indicate the CME is too narrow to be a partial halo, as such it is not expected to be geo- effective. More C-class flares are expected. There is a moderate chance for an M-class flare. Catania sunspot groups 36 and 37 are the main source candidates. Slow solar wind conditions continue, with current solar wind speed measured by ACE being about 310 km/s. The magnitude of the interplanetary magnetic field was maximally 4 nT. Geomagnetic conditions were quiet and are expected to remain as such till the expected arrival of the slow CME of the UT night of 29-30 April, potentially leading to active conditions from early 5 May.
