Bülletään

Decaying NOAA 2612 produced the only flare of the period, a B2.4 flare peaking at 18:22UT. NOAA 2615 was stable and quiet, remaining the most prominent sunspot region on the disk. Some minor coronal dimming was observed in EUV imagery near NOAA 2612 (around 14UT) and NOAA 2615 (around 19UT and 24UT), but no obvious CME seems to have been associated with it. No earth-directed coronal mass ejections (CMEs) were observed in available coronagraphic imagery. The greater than 10MeV proton flux was at nominal levels.

Quiet flaring conditions are expected, with a chance on an isolated C-class event.

Solar wind speed declined from about 370 to 310 km/s, with Bz fluctuating between -4 nT and +4 nT. The interplanetary magnetic field was mostly directed away from the Sun. Solar wind parameters are expected to remain at nominal values. The particle stream from a small positive coronal hole (CH; S15W32) 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. Unsettled conditions are possible on 4 or 5 December in response to the arrival of the CH's particle stream.
