Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 039 Issued at 2200Z on 08 Feb 2001
IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  Solar activity was low. Region 9335 (N09E01) produced a
C1/Sf at 08/2030 UTC. This area has decayed somewhat since yesterday
but contains some mixed polarity fields. Other disk regions have
decayed a little or remain small and simple. Newly numbered Regions
9344 (N31E13) and 9345 (S20E19) emerged on the disk.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low. Region 9335 remains the most likely source of flares.
IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
