Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 014 Issued at 2200Z on 14 Jan 2001
IA.  Analysis of Solar Active Regions and Activity from  13/2100Z
to 14/2100Z:  Solar activity was low.  Mostly optically uncorrelated
minor C-class events occurred during the period.  Region 9306
(N12W25) did produce a C8/Sf at 14/0254Z.  Region 9306 continued to
show growth and is currently an Fac beta-gamma sunspot group with
over 500 millionths of white light area and approximately 60 spots. 
No new regions were numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be low
with an increasing chance of M-Class activity from Region 9306.
IIA.  Geophysical Activity Summary 13/2100Z to 14/2100Z:
The geomagnetic field was quiet to unsettled.  A flilament erupted on
the northwest limb at approximately 14/0430Z.  This event and the
associated CME following was observed in the SOHO/LASCO imagery.  At
this time, most of the energy from this CME does not appear
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled.
