:Product: 0321RSGA.txt :Issued: 2009 Mar 21 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 080 Issued at 2200Z on 21 Mar 2009 IA. Analysis of Solar Active Regions and Activity from 20/2100Z to 21/2100Z: Solar activity was very low. No flares were observed. The visible disk was spotless. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagnetic field was quiet to unsettled. Unsettled conditions were observed between 21/09-15Z. ACE solar wind observations show a continued influence from the recurrent coronal hole. Velocities ranged between 379-455 km/s, and interplanetary Bz ranged from -9 nT and +11 nT. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be predominantly quiet for the next three days (22-24 March). III.
