Bulletin

Five low-level C-class flares were observed. They originated from behind the southwest limb (probably NOAA 2035), from sunspot groups NOAA 2038 and NOAA 2045, and from a region which was still behind the northeast limb. No CMEs with an Earth-directed component were observed. There remains a chance on further C-class flares. Solar wind speed declined from about 430 to 360km/s. Bz was weak and mostly negative at -4nT, with brief excursions up to +2nT. The particle stream from a small equatorial coronal hole that passed the central meridian early on 24 April, is expected to arrive at Earth most probably tomorrow. The geomagnetic field has been quiet and expected to remain so. Locally, a brief active interval is possible from the effect of the coronal hole.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 034, gebaseerd op 12 stations.
