There are currently 8 sunspot regions on the visible solar disk, with small delta’s observed in NOAA 1990 and in the trailing portion of NOAA 1991. The strongest event of the past 24 hours was an impulsive M1-flare peaking at 15:58UT in NOAA 1989, after which this sunspot group decayed significantly.
Most of the C-class flaring occurred in active region NOAA 1986 which has now fully rotated behind the northwest limb. The CMEs associated with these flares were not Earth-directed. Active flaring conditions are expected, with an M-class flare most likely from active regions NOAA 1990 and 1991. Solar wind speed has been varying between 350-360 km/s, and Bz between -5nT and +6nT. A coronal hole on the northern hemisphere is approaching the central meridian and might produce active geomagnetic conditions from late 7 March onwards. Geomagnetic conditions have been quiet and are expected to remain so.
