Bulletin

There are currently 12 sunspot regions on the visible solar disk, with small delta's observed in the trailing portion of NOAA 1991. It was also here that the strongest event of the past 24 hours took place: an impulsive M1-flare peaking at 02:10UT. Two C-flares were produced by NOAA 1986 from behind the west limb, while three C-flares took place in NOAA 1991. Several CMEs were observed. The ones having a (partial) halo, which were first visible in LASCO/C2 at resp. 18:48UT and 21:17UT on 4 March, and 09:24UT on 5 March, were all backside events. None of the observed CMEs has an Earth-directed component, including the CME associated to a filament eruption near the northeast limb (+/- 21:00UT on 4 March). Eruptive flaring conditions are expected, with a small chance for an M-class flare from NOAA 1991. Solar wind speed has gradually increased to values between 400-450 km/s, with Bz varying between -5nT and +5nT. A coronal hole on the northern hemisphere has reached the central meridian and might produce active geomagnetic conditions from 8 March onwards. Geomagnetic conditions have been quiet and are expected to remain so.
