Bulletin

Over the last 24 hours, only 3 C-class flares have been observed, all C1. There are currently 8 sunspot regions on the visible solar disk. Most sunspot groups are stable or decaying, and have a simple magnetic configuration. Some new magnetic flux has emerged in front of NOAA 1990, and merits further monitoring. The most important CMEs that were observed were all related to backside events, including the halo CME first visible in LASCO/C2 at 13:48UT on 5 March. It was associated to a strong flare in the same region that produced another halo CME on 4 March (18:48UT). None of the observed CMEs has an Earth-directed component. Eruptive flaring conditions are expected. Solar wind speed has continued its steady increase and is now varying between 470-500 km/s, with Bz between -5nT and +5nT. The source of this moderate-speed, high-temperature, low-density stream is probably a coronal hole that passed the central meridian on 27 February. Geomagnetic conditions remained quiet. The coronal hole on the northern hemisphere that passed the central meridian early on 5 March might exert its effects starting from 8 March onwards, and may result in active geomagnetic conditions. Until then, quiet geomagnetic conditions are expected to continue.
