:Product: 1110RSGA.txt :Issued: 2006 Nov 10 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 314 Issued at 2200Z on 10 Nov 2006 IA. Analysis of Solar Active Regions and Activity from 09/2100Z to 10/2100Z: Solar activity was very low. Region 923 (S06E58) has not produced any activity over the past 24 hours. Region 921 has rotated off the solar disk. IB. Solar Activity Forecast: Solar activity is expected to be very low to low for the next three days. IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic field was at unsettled to major storm levels. Elevated solar wind speed due to the coronal hole high speed stream, combined with Bz varying between +/- 10 nT, produced multiple major storm periods at high latitudes. Solar wind speed remains elevated at approximately 600 km/s. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be unsettled to active on 11 November as the coronal hole high speed stream wanes. Expect quiet to unsettled conditions on 12-13 November. III. Event Probabilities 11 Nov-13 Nov Class M 05/05/05 Class X 01/01/01 Proton 01/01/01 PCAF green IV.
