Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 252 Issued at 2200Z on 08 Sep 2008
IA.  Analysis of Solar Active Regions and Activity from  07/2100Z
to 08/2100Z:  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 07/2100Z to 08/2100Z:
Geomagnetic field activity was at quiet to unsettled levels. ACE
solar wind data indicated Earth remained within a recurrent coronal
hole high-speed stream. However, solar wind velocities gradually
decreased from a high of 624 km/sec at 07/2131Z to a low of 534
km/sec at 08/2043Z. 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 predominantly quiet levels through the forecast
period (09 - 11 September).
