Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 364 Issued at 2200Z on 30 Dec 2010
IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 30/2100Z:  Solar activity was very low during the past 24 hours. A
partial-halo CME was observed on SOHO LASCO C2 imagery, first
visible at 30/1000Z, that was associated with a filament eruption
centered at N36W50. The CME does not appear to be Earth-directed.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low with a slight chance for C-class activity for the next three
days (31 December - 2 January).
IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z:
The geomagnetic field was at quiet to unsettled levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to quiet for the next three days (31 December - 2 January).
