:Product: 0514RSGA.txt :Issued: 2007 May 14 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 134 Issued at 2200Z on 14 May 2007 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was at very low levels. Newly numbered Region 956 (N02E61) produced several low level B-class flares during the period. This region rapidly grew into a Cao beta magnetic sunspot group. Region 955 (S09W45) underwent little change during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be at very low levels. Emerging Region 956 may further develop this period to produce isolated C-class flares. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was at quiet levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at predominantly quiet levels with isolated unsettled conditions possible throughout the forecast period. III.
