Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 300 Issued at 2200Z on 26 Oct 2008
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.  The visible solar disk
remains spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was at quiet levels.  Solar wind observations
from the ACE spacecraft show a steady increase in velocity from
around 290 km/s to 390 km/s between  26/0400Z to 26/0800Z.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet for 27 October.  Quiet to unsettled
levels with isolated active conditions are expected for 28 October. 
Predominately unsettled levels with isolated active periods, and
possible isolated minor storm conditions at high latitudes, are
forecast for 29 October.  The increase in activity is due to a
recurrent coronal hole high speed stream rotating into a
geoeffective position.
