:Product: 0704RSGA.txt :Issued: 2010 Jul 04 2200 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 185 Issued at 2200Z on 04 Jul 2010 IA. Analysis of Solar Active Regions and Activity from 03/2100Z to 04/2100Z: Solar activity was very low. Region 1084 (S19W32) was quiet and stable. A new, emerging flux region was observed near N19W38. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels for the next three days (05 - 07 July). IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic field was quiet. Solar wind velocity was steady at about 600 km/s through 04/0700Z when speeds gradually decayed to near 500 km/s by the end of the summary period. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet for the next three days (05 - 07 July). III.
