Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 032 Issued at 2200Z on 01 Feb 2008
IA.  Analysis of Solar Active Regions and Activity from  31/2100Z
to 01/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 31/2100Z to 01/2100Z:
The geomagnetic field was quiet to active.  Solar wind measurements
at the ACE spacecraft indicated signatures consistent with a co
rotating interaction region around 31/0900Z.  This was followed by a
coronal hole high speed stream commencing around 31/21Z.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be unsettled with isolated periods of active conditions
due to the influence of the coronal hole high speed stream.
