Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 203 Issued at 2200Z on 22 Jul 2010
IA.  Analysis of Solar Active Regions and Activity from  21/2100Z
to 22/2100Z:  Solar activity was very low. Todays activity consisted
of occasional mid-level and upper level B-class flares. Most of
these were from Region 1089 (S23E33) although Region 1087 (N18,
rotated beyond west limb) also contributed. Activity appeared to be
on a general decreasing trend during the last few hours of the
period. Region 1089 appeared to be simplifying somewhat and showed a
slight decline in overall sunspot area.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low to low for the next three days (23-25 July).
IIA.  Geophysical Activity Summary 21/2100Z to 22/2100Z:
The geomagnetic field was quiet.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be unsettled for the next two days (23-24 July). The
increase is expected due to a favorably positioned coronal hole.
Quiet to unsettled levels are expected for 25 July.
