Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 070 Issued at 2200Z on 10 Mar 2008
IA.  Analysis of Solar Active Regions and Activity from  09/2100Z
to 10/2100Z:  Solar activity was very low. Region 985 (S10W83) was
numbered today. It is currently a BXO group with an area of 90
millionths.
IB.  Solar Activity Forecast:  Solar activity is expected to continue
at very low levels.
IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z:
The geomagnetic field was at quiet to active levels due to the
influence of a recurrent coronal hole high speed stream. Solar wind
at the ACE spacecraft is elevated to approximately 700 km/s at
forecast issue time.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from quiet to active levels with isolated minor
storm periods possible for days one and two (11-12 March). Quiet to
unsettled conditions are expected on day three (13 March) as the
effects of the coronal hole high speed stream wane.
