Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 207 Issued at 2200Z on 26 Jul 2006
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.  Region 901 (N06E15) has
produced only B-class activity.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low for the next three days (27 - 29 July).
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the next three days (27 - 29
July).  A coronal hole in the northern hemisphere is not expected to
be geoeffective, but may produce isolated active periods on 27 July.
