Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 299 Issued at 2200Z on 26 Oct 2007
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field ranged from quiet to active conditions.  The
solar wind data observed at the ACE spacecraft indicates the
presence of the coronal hole high speed wind stream.  Speeds have
averaged around 670 km/s with Bz fluctuations between +/- 4 nT.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be predominately unsettled with isolated active
conditions due to the influence of the coronal hole high speed
stream.
