:Product: 0414RSGA.txt :Issued: 2009 Apr 14 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 104 Issued at 2200Z on 14 Apr 2009 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was very low. No flares were observed during the past 24 hours. The solar disk remains spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was quiet. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels for 15-16 April. Quiet to unsettled conditions are expected for 17 April due to a recurrent coronal hole high speed stream. III.
