Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 207 Issued at 2200Z on 26 Jul 2005
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity has been very low.  Region 791 (N13E09)
has produced several B-class flares during the last 24 hours.  Three
backside CME's were observed on LASCO imagery during the period. 
None appear to be Earth directed.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low.  A chance for an isolated C-class event is possible from
Region 791.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was predominately quiet with one period of
unsettled conditions at middle latitudes.  The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled with isolated active conditions
possible.  These effects are possible as a recurrent coronal hole
high speed solar wind stream moves into geoeffective position.
