Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 271 Issued at 2200Z on 27 Sep 2008
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was at very low levels.  The visible
solar disk was spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was at quiet levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at mostly quiet levels for the next three days (28 to
30 September).  There is a chance for unsettled periods on days two
and three due to a recurrent solar wind stream expected to begin
influencing the geomagnetic field.  On day three there is a slight
chance for an isolated active period at high latitudes.
