Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 069 Issued at 2200Z on 09 Mar 2008
IA.  Analysis of Solar Active Regions and Activity from  08/2100Z
to 09/2100Z:  Solar activity was very low. The visible disk is
spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to continue
at very low levels.
IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z:
The geomagnetic field was at quiet to minor storm levels due to the
influence of a recurrent coronal hole high speed stream. Solar wind
at the ACE spacecraft increased from 438 km/s to a maximum of 691
km/s at 09/2023Z.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from quiet to active levels with isolated minor
storm periods possible for the next three days (10 - 12 March), due
to the coronal hole high speed stream.  Isolated major storm
conditions are possible at high latitudes during this period.
