Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 176 Issued at 2200Z on 25 Jun 2006
IA.  Analysis of Solar Active Regions and Activity from  24/2100Z
to 25/2100Z:  Solar activity was very low.  New Region 897 (N06E75)
produced six B-class flares in the last 24 hours.  The largest was a
B4 at 25/0505Z.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.  There is a slight chance of a C-class flare from Region 897.
IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z:
The geomagnetic field was quiet to unsettled.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the first two days (26-27
June).  A recurrent coronal hole is expected to rotate into
geoeffective position on 28 June.  Unsettled to active conditions,
with possible minor storm periods, are expected.
