:Product: 0103RSGA.txt :Issued: 2008 Jan 03 2340 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 003 Issued at 2200Z on 03 Jan 2008 IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity was very low. No significant flares occurred during the past 24 hours. Region 980 (S06E42) has decayed to an Hsx alpha sunspot group. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. A chance remains for an isolated C-class flare from Region 980. IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated active periods for the next two days (4-5 January). This elevated activity may result from transients associated with recent C-class flares. Predominantly quiet conditions should return on 6 January. III.
