Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 250 Issued at 2200Z on 06 Sep 2008
IA.  Analysis of Solar Active Regions and Activity from  05/2100Z
to 06/2100Z:  Solar activity was very low. No flares occurred during
the past 24 hours and the solar disk continues to be spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 05/2100Z to 06/2100Z:
The geomagnetic field was mostly quiet with some isolated unsettled
to active periods. Solar wind speed as observed by ACE continued to
be elevated throughout the day, with values ranging between 480 to
560 km/s. The greater than 2 MeV electron flux at geosynchronous
orbit reached high levels during the last 24 hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the first day (07 September)
and is expected to be predominantly quiet for the second and third
days (08-09 September).
