:Product: 0714RSGA.txt :Issued: 2007 Jul 15 0103 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 195 Issued at 2200Z on 14 Jul 2007 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was very low. No significant flares occurred during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low, with a slight chance for an isolated C-class flare. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was predominantly quiet to active. A single period of minor storming occurred at high latitudes between 14/1800Z and 2100Z due to a coronal hole high speed stream. Solar wind speed at ACE reached a peak of 561 km/s at 14/2121Z. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled on 15 July. Quiet conditions are expected on 16-17 July. III.
