:Product: 0108RSGA.txt :Issued: 2008 Jan 08 2215 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 008 Issued at 2200Z on 08 Jan 2008 IA. Analysis of Solar Active Regions and Activity from 07/2100Z to 08/2100Z: Solar activity was very low. No flares occurred during the last 24 hours. Region 980 (S08W23) decayed throughout the period. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: The geomagnetic field was mostly quiet to unsettled during the past 24 hours. Solar wind speeds remain elevated but are slowly declining. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the first day (09 January). Conditions should be predominantly quiet for the second and third days (10-11 January) III. Event Probabilities 09 Jan-11 Jan Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
