Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 001 Issued at 2200Z on 01 Jan 2010
IA. Analysis of Solar Active Regions and Activity from 31/2100Z
to 01/2100Z: Solar activity was very low. Region 1039 (S27W35)
produced several B-flares during the forecast period. This region
remains a D-type sunspot group with a beta magnetic classification.
IB. Solar Activity Forecast: Solar activity is expected to be very
low to low. There is a chance of an isolated C-flare from Region
1039.
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was quiet.
IIB. Geophysical Activity Forecast: The geomagnetic field is
expected to be quiet for the next three days (02 – 04 January).
