Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 115 Issued at 2200Z on 25 Apr 2006
IA.  Analysis of Solar Active Regions and Activity from  24/2100Z
to 25/2100Z:  Solar activity was low. Region 875 (S10E46), a beta
gamma delta magnetic group, produced a long duration C1 flare at
25/0726 UTC. An associated CME was observed in LASCO imagery off the
east limb with a speed of approximately 520 Km/s. This CME is not
expected to be geoeffective.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low. An isolated M-class flare is possible from Region 875.
IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was mostly quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be mostly quiet.
