Bulletin

Eleven C-class flares were observed, with 6 produced by NOAA 2035 and the other 5 by NOAA 2038. NOAA 2035 produced the strongest flare at the end of the period (C8 peaking at 11:37UT). The strongest flare from NOAA 2038 was a C5 flare peaking at 20:02UT (21 April). Together with NOAA 2045, these active regions have increased somewhat in sunspot area and magnetic complexity. The other sunspot regions are stable and/or rounding the west limb. Based on the currently available SOHO and STEREO coronagraphic imagery, no earth-directed CMEs have been observed. Further C-class flaring is expected, with a chance on an isolated M-flare. Solar wind speed declined further from around 600 to 450km/s. Bz was mostly positive, with values up to +5nT. Geomagnetic conditions evolved from active to quiet. Geomagnetic conditions are expected to remain mostly quiet.

Die heute international geschätzte Sonnenfleckenanzahl (ISN): 102, basierend auf 14 Stationen.
