Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 086 Issued at 2200Z on 27 Mar 2007
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was very low.  Region 948 (S02W56) has
decayed into a unipolar region.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
The geomagnetic field was quiet to active.  Solar wind speed
increased to approximately 550 km/s due to the coronal hole high
speed stream.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the next three days (28 - 30
March).  Isolated active periods are possible on 28 March due to the
coronal hole high speed stream.
