Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 001 Issued at 2200Z on 01 Jan 2008

IA. Analysis of Solar Active Regions and Activity from 31/2100Z to 01/2100Z: Solar activity was low. Region 980 (S07E69) produced a C1/Sf flare at 01/1537Z. As the region rotates onto the east limb, its initial classification is a simple Axx alpha group.

IB. Solar Activity Forecast: Solar activity is expected to be very low to low. There is a chance for an isolated M-class event from Region 980.

IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic field was quiet.

IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain quiet for the forecast period.
