Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 248 Issued at 2200Z on 05 Sep 2010
IA.  Analysis of Solar Active Regions and Activity from  04/2100Z
to 05/2100Z:  Solar activity was very low.  Regions 1101 (N13W88) and
1105 (N19W52) produced several B-class events  during the period.
IB.  Solar Activity Forecast:  Solar activity is forecast to be low
for the next 3 days (6-8 September) with a chance for  C-class
events and a slight chance for M-class events.
IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
forecast to range from quiet to active conditions for days 1-2
(06-07 September). Conditions are forecast to return to quiet
conditions on day 3 (08 September).
