Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 270 Issued at 2200Z on 26 Sep 2008
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was at very low levels.  The visible
solar disk was spotless as Region 1002 (N26W79) decayed to plage.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was at quiet levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet levels for all three days (27 to 29
September).  There is a slight chance for isolated unsettled periods
on day three, as a recurrent solar wind stream rotates into a
geoeffective position.
