:Product: 0122RSGA.txt :Issued: 2006 Jan 22 2203 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 022 Issued at 2200Z on 22 Jan 2006 IA. Analysis of Solar Active Regions and Activity from 21/2100Z to 22/2100Z: Solar activity increased to low levels. Region 848 (S19W15) produced multiple B and C-class flares during the period, the largest event was a C4 x-ray flare occurring at 22/1410Z. A weak delta spot is evident near the central cluster of intermediate spots. Region 849 (S07E44) was numbered today. IB. Solar Activity Forecast: Solar activity is expected to be at low to moderate levels. Region 848 has the potential of producing isolated M-class flares. IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic field was at quiet to unsettled levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at predominantly quiet to unsettled levels. Isolated active conditions are possible on 23 and 24 January due to a recurrent coronal hole high speed stream. III.
