Bulletin

Over the last 24 hours, no C-class flares were observed, with x-ray background around B6-level. There are currently 9 sunspot regions on the visible solar disk. Most sunspot groups are stable or decaying. Eruptive flaring conditions are expected, with most chance on a C-flare from sunspot group NOAA 1996. A CME was observed by LASCO/C2 on 6 March at 13:36UT, and was associated to a filament eruption in the southeast solar quadrant. Current imagery indicates it did not have an Earth directed component. Over the last 24 hours, solar wind speed has gradually decreased to values near 410 km/s, with Bz varying between -4nT and +4nT. Geomagnetic conditions have been quiet and are expected to remain so until the arrival of a high speed wind stream from the coronal hole that passed the central meridian early on 5 March. This may result in episodes of active geomagnetic conditions starting 8-9 March.

Het geschatte internationale zonnevlekkengetal (ISN) van vandaag: 093, gebaseerd op 17 stations.
