Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 005 Issued at 2200Z on 05 Jan 2010
IA. Analysis of Solar Active Regions and Activity from 04/2100Z
to 05/2100Z: Solar activity was very low. Early observations
indicated that Region 1039 (S29W90) remained a D-type sunspot group
with a beta magnetic classification. However, later observations
report the region as spotless as it rotates toward the west limb.
IB. Solar Activity Forecast: Solar activity is expected to be very
low.
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be predominantly quiet for the next three days (06-08
January).
