:Product: 20001214RSGA.txt :Issued: 2000 Dec 14 2200 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 349 Issued at 2200Z on 14 Dec 2000 IA. Analysis of Solar Active Regions and Activity from 13/2100Z to 14/2100Z: Solar activity was low, with only minor C-class events observed within the past 24 hours. Of the ten spotted regions currently on the visible disk, Regions 9264 (S24E16) and 9267 (N07W02) have been the originators for most recent flare activity, the largest being a C6/Sf from Region 9267 at 14/1523Z. IB. Solar Activity Forecast: Solar activity is expected to be low, with the possibility for an isolated minor M-class event, for the next three days. IIA. Geophysical Activity Summary 13/2100Z to 14/2100Z: The geomagnetic field was quiet at all latitudes for the past 24 hours. The greater than 2 MeV flux continued it's recent daily fluctuation between low and moderate levels. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet, with isolated periods of unsettled conditions, for the next three days. III.
