:Product: 0621RSGA.txt :Issued: 2009 Jun 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 172 Issued at 2200Z on 21 Jun 2009 IA. Analysis of Solar Active Regions and Activity from 20/2100Z to 21/2100Z: Solar activity was very low. No flares were observed. New Region 1022 (S27E15) was numbered during the period. The region emerged on the disk as a 2-spot, bi-polar Bxo beta spot group. The region has been quiet and stable. IB. Solar Activity Forecast: Solar activity is expected to remain at very low levels for the next three days (22 - 24 June). IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: The geomagetic field was at quiet to unsettled levels. A brief period of sustained negative Bz, from about 20/2100Z to 21/0200Z, resulted in unsettled geomagnetic conditions observed at all latitudes. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet for the next three days (22 - 24 June). III.
