:Product: 1116RSGA.txt :Issued: 2010 Nov 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 320 Issued at 2200Z on 16 Nov 2010 IA. Analysis of Solar Active Regions and Activity from 15/2100Z to 16/2100Z: Solar activity has been very low. Region 1126 (S32E20) produced a few small B-class flares. New Region 1127 (N25E71) rotated onto the visible disk. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. There is a chance of a C-class flare from Region 1126 over the next three days (17-19 November). IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit reached high levels during the period. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (17-19 November). III.
