:Product: 1016RSGA.txt :Issued: 2008 Oct 16 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 290 Issued at 2200Z on 16 Oct 2008 IA. Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity was very low with no flares observed. Region 1005 (N26W29) was quiet and stable during the period. Region 1006 (S27W63) was numbered today and is an alpha magnetic configuration. This region exhibits New Cycle 24 magnetic polarity. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field was mostly quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels again today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet all three days of the forecast period (17 - 19 October). III.
