Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 341 Issued at 2200Z on 06 Dec 2008
IA.  Analysis of Solar Active Regions and Activity from  05/2100Z
to 06/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
very low.
IIA.  Geophysical Activity Summary 05/2100Z to 06/2100Z:
The geomagnetic field was mostly quiet to active.  A brief period 
(06-09Z) of minor storm conditions at mid latitudes and major storm
conditions at high latitudes was observed as solar wind speeds at
ACE increased above 500 km/s.  The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominantly quiet as the coronal hole high speed
stream wanes.
