:Product: 20040610RSGA.txt :Issued: 2004 Jun 10 2200 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 162 Issued at 2200Z on 10 Jun 2004 IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity has been very low. Region 622 (S11W72) developed into a 4 spot group with a Beta magnetic classification, but continues to have minimal potential for flare activity. IB. Solar Activity Forecast: Solar activity is expected to remain very low. IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field has been at quiet to usettled levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain at quiet to unsettled levels through 13 June. There is a slight chance for an isolated period of active levels on 11 June due to a possible solar sector boundary crossing. III.
