Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 196 Issued at 2200Z on 15 Jul 2007
IA.  Analysis of Solar Active Regions and Activity from  14/2100Z
to 15/2100Z:  Solar activity was very low.  No significant activity
has been observed during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low, with a slight chance for an isolated C-class flare.
IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z:
The geomagnetic field ranged from quiet to active.  Solar wind speed
decreased throughout the day to approximately 480 km/s at 15/2100Z.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled for the next three days (16 - 18
July).
