Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 200 Issued at 2200Z on 18 Jul 2008
IA.  Analysis of Solar Active Regions and Activity from  17/2100Z
to 18/2100Z:  Solar activity was at very low levels.  New Region 1000
(S13E24) was numbered during the period.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 17/2100Z to 18/2100Z:
The geomagnetic field was at mostly quiet levels.  Solar wind speed,
as measured at the ACE spacecraft, continued its gradual decrease in
velocities from about 460 km/s at the beginning of the period, to
about 350 km/s by forecast issue time.  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 mostly quiet for the next three days (19 - 21 July).
