Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 255 Issued at 2200Z on 11 Sep 2008
IA.  Analysis of Solar Active Regions and Activity from  10/2100Z
to 11/2100Z:  Solar activity was very low. New Region 1001 (N06E14)
was numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 10/2100Z to 11/2100Z:
The geomagnetic field was quiet.  The greater than 2 MeV electron
flux at geosynchronous orbit was at high levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels for 12 September.  Quiet to unsettled
conditions are forecast for 13 September, with unsettled to active
conditions expected for 14 September.  The increase in activity is
forecast due to a recurrent coronal hole high speed stream.
