Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 205 Issued at 2200Z on 24 Jul 2005
IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity has been very low.  Region 791 (N13E36)
remains the only numbered spot group on the solar disk.  This region
has shown a slight growth in area and maintains a simple beta
magnetic configuration.  Several CME's were observed by LASCO
imagery over the past 24 hours.  Analysis show these were backside
events and not Earth directed.  One appears to be a halo CME first
observed by C2 imagery at 24/1354 UTC with an associated Type II
radio sweep.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low.  There is a chance for an isolated C-class flare from
Region 791.
IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
The geomagnetic field has been quiet to unsettled.  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 at quiet to unsettled levels.
