Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 011 Issued at 2200Z on 11 Jan 2001
IA.  Analysis of Solar Active Regions and Activity from  10/2100Z
to 11/2100Z:  Solar activity was low. Only three isolated C-class
events occurred during the period. The largest was a C1/SF event
from Region 9308 (N14E39) at 10/0215 UTC. Region 9306 (N12E14)
developed into a more complex Beta-Gamma magnetic configuration
during the period but showed little activity during that time. One
new region was numbered, 9309 (N09W16).
IB.  Solar Activity Forecast:  Solar activity is expected to persist
at low levels with possible isolated M-class events possible.
IIA.  Geophysical Activity Summary 10/2100Z to 11/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
