NOAA 2222 continues its steady growth, with some magnetic polarity mixing in the middle portion and just behind the main leading spot. It produced 3 C-class flares, including the strongest event of the last 24 hours (an impulsive C6.7 peaking at 08:21UT). Nearly spotless NOAA 2224 (Catania 22) and NOAA 2219 produced resp. 1 and 4 C-class flares. The other sunspot regions were quiet, with an active region rounding the southeast limb. A large filament on the northern hemisphere just west of the central meridian erupted on 28 November between 14:30 and 17:00UT. The eruption may have been triggered by some activity in reversed polarity region NOAA 2223, at the south end of the filament. There does not seem to be an obvious CME associated to this event. None of the observed CMEs is Earth directed. C-class flaring is expected, with a small chance on low- level M-class flares. Solar wind speed varied between 350 and 410 km/s. The IMF is directed towards the Sun, with Bz mostly positive varying between 0 and +12 nT. Brief negative excursions to -12 nT were observed near 12:00UT (28 November) and between 03:00-04:00UT (29 November). The geomagnetic field was quiet to unsettled (K<4) and is expected to remain so.
