Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 101 Issued at 2200Z on 10 Apr 2008
IA.  Analysis of Solar Active Regions and Activity from  09/2100Z
to 10/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z:
The geomagnetic field ranged from quiet to unsettled.  Solar wind
speed remains elevated to greater than 600 km/sec due to the
continued influence of a coronal hole high speed stream.  The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels again today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled 11 April and abate to
predominately quiet for 12 - 13 April as the coronal hole high speed
stream rotates out of its geoeffective position.
