Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 201 Issued at 2200Z on 19 Jul 2008
IA.  Analysis of Solar Active Regions and Activity from  18/2100Z
to 19/2100Z:  Solar activity was at very low levels.  Region 1000
(S12E10) was quiet and stable.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 18/2100Z to 19/2100Z:
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 quiet on day one (20 July), and quiet to unsettled on
days two and three (21 - 22 July), as a recurrent coronal hole high
speed stream is expected to rotate into a geoeffective position.
