Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 254 Issued at 2200Z on 10 Sep 2008
IA.  Analysis of Solar Active Regions and Activity from  09/2100Z
to 10/2100Z:  Solar activity was very low. No flares were observed.
The visible disk remained spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z:
Geomagnetic field activity was at quiet to briefly unsettled levels.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels during the period.
IIB.  Geophysical Activity Forecast:  Geomagnetic field activity is
expected to be at quiet levels during days 1 - 2 (11 -12 September).
Activity is expected to increase to unsettled levels on day 3 (13
September) as a recurrent coronal hole high-speed stream begins to
influence the field.
