Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 363 Issued at 2200Z on 29 Dec 2010
IA.  Analysis of Solar Active Regions and Activity from  28/2100Z
to 29/2100Z:  Solar activity was very low. Two low-level B-class
X-ray events were observed during the period, both on the east limb.
The first event was near S30 and the second event was near N32. New
Region 1139 (S26E48) was numbered as a simple bi-polar sunspot
group. The remainder of the disk and limb was quiet and stable.
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 (30 December - 1 January).
IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (30 December - 1
January).
