Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 071 Issued at 2200Z on 12 Mar 2007
IA.  Analysis of Solar Active Regions and Activity from  11/2100Z
to 12/2100Z:  Solar activity remained at very low levels.  No flares
were recorded during the period.  Region 946 (N10W72) underwent
decay and is classified as an Hsx alpha sunspot group.  No new
regions were numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 11/2100Z to 12/2100Z:
The geomagnetic field was at quiet to active levels.  The elevated
conditions were due to the onset of a recurrent coronal hole high
speed stream.  Solar wind speeds have steadily increased to
approximately 570 km/sec at the time of this writing.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from quiet to active levels.  Isolated minor storm
conditions are possible on 13 March due to a recurrent coronal hole.
Predominantly unsettled to active levels are expected on 14 March. 
A return to quiet to unsettled conditions are expected on 15 March
as the coronal hole wanes.
