Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 038 Issued at 2200Z on 07 Feb 2001
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was low. Only a few C-class flares
occurred, all without reported optical flares. All of the sunspot
groups currently on the disk are relatively small and magnetically
simple. New Region 9343 (N03E08) was numbered.
IB.  Solar Activity Forecast:  Solar activity is expected to be low.
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was quiet to unsettled. Solar wind information
suggests that the high speed stream observed on 06 Feb is passing,
returning solar wind parameters to nominal levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
