Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 342 Issued at 2200Z on 07 Dec 2008
IA.  Analysis of Solar Active Regions and Activity from  06/2100Z
to 07/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 06/2100Z to 07/2100Z:
The geomagnetic field was at quiet to unsettled levels.  Observations
at the ACE satellite indicate a continued slight influence from the
coronal hole high speed stream.  Solar wind speeds have ranged from
580 km/s down to 520 km/s during the past 24 hours.  The greater
than 2 MeV electron flux at geosynchronous orbit was at high levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominately quiet for the forecast period (08-10
December) as the high speed stream subsides.
