Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 269 Issued at 2200Z on 25 Sep 2004
IA.  Analysis of Solar Active Regions and Activity from  24/2100Z
to 25/2100Z:  Solar activity was at very low levels today.  Region
673  (S13W57) was responsible for some very minor activity today. 
This region continues to exhibit decay and is now a two spot alpha
magnetic group.  Region 675 (S08E75) was numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be at
very low levels throughout the period.
IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was at quiet to unsettled levels today.  The
greater than 2 MeV electron flux at geosynchronous orbit reached
high levels today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled levels throughout the period.
