Bulletin
Only two B-class flares were observed during the period, the strongest a B2.9 at 17:11UT by NOAA 2612. There are currently 4 sunspot groups visible on the solar disk, mostly small and with relatively simple magnetic configurations. NOAA 2615 remains the most prominent and complex region. 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 parameters were at nominal levels, except during the brief passage of a transient structure around midnight. Current solar wind speed values are around 380 km/s. Bz has been fluctuating between -3 nT and +4 nT during the entire period. 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; S15W18) 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.
