Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 287 Issued at 2200Z on 14 Oct 2001
IA.  Analysis of Solar Active Regions and Activity from  13/2100Z
to 14/2100Z:  Solar activity was low. Only a few, small C-class
flares were observed, mostly in Region 9661 (N15E30). This remains
the largest sunspot group on the visible disk and has maintained its
beta-delta magnetic configuration. New Regions 9666 (S12E31) and
9667 (N24E73) were numbered.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
to moderate. Region 9661 appears to be capable of an isolated major
IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
