Bulletin

NOAA 2615 remained the only flare-active sunspot region on the disk. It produced the two sole C-class events of the period, a C1 flare at 15:07UT and a C2 flare at 15:25UT. NOAA 2612 and NOAA 2614 are further decaying and were quiet. The filament north of NOAA 2612 (N15W15) erupted between 13:30 and 14:30UT. Coronal dimming was observed, but the coronagraphic images do not show an obvious coronal mass ejection. In H-alpha, a nearby filament blob (N35W15) quietly disappeared in the subsequent hours. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

There's still a chance on an isolated C-class flare.

Solar wind parameters are at nominal levels, with wind speed values mostly between 340 and 370 km/s and Bz fluctuating between -4 nT and +5 nT. The interplanetary magnetic field was mostly directed away from the Sun. Solar wind parameters are expected to remain at nominal values. A small positive coronal hole (S15W00) is near the central meridian and may mildly affect the earth-environment late on 4 or on 5 December.

The geomagnetic field was at quiet levels and is expected to remain so.
