:Product: 0711RSGA.txt :Issued: 2006 Jul 11 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 192 Issued at 2200Z on 11 Jul 2006 IA. Analysis of Solar Active Regions and Activity from 10/2100Z to 11/2100Z: Solar activity was at very low levels. Region 899 (S06W18) underwent penumbral decay during the past 24 hours. No new regions were numbered today. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels. IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: The geomagnetic field was at quiet to unsettled levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at unsettled to minor storm levels with isolated major storm conditions possible on 12 July due to a recurrent high speed coronal hole stream. A return to quiet to unsettled levels is expected on 13 and 14 July as the coronal hole moves out of a geoeffective position. III.
