:Product: 0111RSGA.txt :Issued: 2008 Jan 11 2203 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 011 Issued at 2200Z on 11 Jan 2008 IA. Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity was very low. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field was quiet. The greater than 2 MeV proton flux at geosynchronous orbit was at high levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled with isolated active conditions on 12-13 January due to a recurrent coronal hole. Conditions are expected to be predominately unsettled for 14 January. III. Event Probabilities 12 Jan-14 Jan Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
