:Product: 0707RSGA.txt :Issued: 2008 Jul 07 2203 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 189 Issued at 2200Z on 07 Jul 2008 IA. Analysis of Solar Active Regions and Activity from 06/2100Z to 07/2100Z: Solar activity was very low. No flares were observed. The visible disk was spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 06/2100Z to 07/2100Z: Geomagnetic field activity was at quiet levels. IIB. Geophysical Activity Forecast: Geomagnetic field activity is expected to be at quiet levels during days 1 - 2 (July 08 - 09). Activity is expected to increase to unsettled levels on day 3 (10 July) with active levels possible at high latitudes due to a corotating interaction region in advance of a recurrent coronal hole high-speed stream.
