:Product: 0306RSGA.txt :Issued: 2007 Mar 06 2203 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Environment Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 065 Issued at 2200Z on 06 Mar 2007 IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity was very low. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field was mostly quiet to active. A single period of minor storming was observed at all latitudes from 06/0300 - 0600Z. Solar wind speed has been increasing to approximately 580 km/s throughout the day, indicating the arrival of a coronal hole high speed stream. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated active periods on 07 March due to the recurrent coronal hole. Expect quiet conditions on 08 - 09 March as the coronal hole rotates out of its geoeffective position. III.
