公告

There are currently 7 sunspot groups visible, all are small and have a simple magnetic configuration. Five C-class flares were recorded. The strongest was a C3-flare peaking at 00:07UT in a new region near the southeast limb. The two most notable CMEs detected over the last 24 hours, seen first by LASCO/C2 at resp. 12:12UT and 13:36UT, are related to backside events and have no Earth-directed component. Eruptive flaring conditions are expected. Over the last 24 hours, solar wind speed has gradually decreased to values near 370-400 km/s, with Bz varying between -4nT and +4nT. A small coronal hole on the southern hemisphere may reach the central meridian (CM) early on 9 March with possible geomagnetic influences on 12-13 March. Geomagnetic conditions have been quiet and are expected to remain so until the arrival of the coronal hole solar wind stream (CM passage 5 March). This may result in episodes of active geomagnetic conditions starting later today or tomorrow 9 March.
