:Product: 0505RSGA.txt :Issued: 2006 May 05 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 125 Issued at 2200Z on 05 May 2006 IA. Analysis of Solar Active Regions and Activity from 04/2100Z to 05/2100Z: Solar activity decreased to very low levels. Regions 875 (S13W85) and 880 (S08E50) were limited to minor B-class flare activity. Region 881 (S12E75) was numbered today. IB. Solar Activity Forecast: Solar activity is expected to be at very low to low levels. IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic field ranged from quiet to minor storm levels. The elevated conditions were due to a co-rotating interaction region. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to range from quiet to minor storm levels, possibly isolated severe storm conditions on 06 May due to a recurrent high speed coronal hole stream. Predominantly unsettled to active conditions are expected on 07 and 08 May due to continued coronal hole effects. III.
