Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 217 Issued at 2200Z on 05 Aug 2009
IA.  Analysis of Solar Active Regions and Activity from  04/2100Z
to 05/2100Z:  Solar activity was very low.  No flares occurred during
the past 24 hours.  The visible disk was spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field  is
expected to be mostly quiet to unsettled with a slight chance for
isolated active periods on day one (06 August) due to effects of a
recurring coronal hole.  Quiet conditions are expected on days two
and three (07 – 08 August).
