:Product: 0629RSGA.txt :Issued: 2007 Jun 29 2202 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 180 Issued at 2200Z on 29 Jun 2007 IA. Analysis of Solar Active Regions and Activity from 28/2100Z to 29/2100Z: Solar activity was low. Region 962 (S10E55) produced a C1 flare at 29/2013Z. Region 961 (S13E23) remains relatively unchanged since yesterday. IB. Solar Activity Forecast: Solar activity is expected to be very low to low. There is a chance for C-class activity from either Region 961 or 962. IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic field ranged from quiet to unsettled. Solar wind speed increased to approximately 500 km/s as a recurrent coronal hole rotated into a geoeffective position. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled for the next three days (30 June - 02 July). Isolated active periods are possible on 30 June and 01 July due to the coronal hole high speed stream. III.
