Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 202 Issued at 2200Z on 20 Jul 2008
IA.  Analysis of Solar Active Regions and Activity from  19/2100Z
to 20/2100Z:  Solar activity was at very low levels.  Region 1000
(S12W05) remained quiet and stable.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field was quiet.  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 to unsettled all three days of the
forecast period (21 - 23 July) with isolated active periods possible
on day three.  The forecasted increase in activity is a result of a
recurrent coronal hole high speed stream that is expected to rotate
into a geoeffective position.
