:Product: 0609RSGA.txt :Issued: 2010 Jun 10 1135 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 160 Issued at 2200Z on 09 Jun 2010 IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was very low. Region 1078 (S21W60) has grown in size and magnetic complexity over the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low to low with a chance for a C-class event from Region 1078 during the next 3 days (10-12 June). IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was quiet for the past 24 hours. The greater than 2 MeV electron flux at geosynchronous orbit was at high levels during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is forecast to be mostly quiet with a chance for an isolated period of unsettled conditions during the next 3 days (10-12 June). III.
