:Product: 0214RSGA.txt :Issued: 2008 Feb 14 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 045 Issued at 2200Z on 14 Feb 2008 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was at very low levels. The visible disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was predominately quiet to unsettled due to a geoeffective coronal hole high speed stream. Solar wind speed remains in excess of 600 km/s. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled, with possible isolated active conditions, 15 - 16 February due to the continued influence of the coronal hole high speed stream. On 17 February conditions are expected to abate to quiet. III. Event Probabilities 15 Feb-17 Feb Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
