:Product: 0115RSGA.txt :Issued: 2006 Jan 15 2204 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Environment Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 015 Issued at 2200Z on 15 Jan 2006 IA. Analysis of Solar Active Regions and Activity from 14/2100Z to 15/2100Z: Solar activity has been low. Two new regions were numbered today; Region 847 (S09W08) which produced a C1 flare at 15/1445Z and Region 846 (N05W30) which has developed from a plage region into a Dso Beta group. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. IIA. Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic field was quiet. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly unsettled with a chance for active periods on 16 January due to a geoeffective coronal hole high speed stream. Quiet to unsettled conditions are expected on 17 - 18 January. III. Event Probabilities 16 Jan-18 Jan Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
