Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 114 Issued at 2200Z on 24 Apr 2007
IA.  Analysis of Solar Active Regions and Activity from  23/2100Z
to 24/2100Z:  Solar activity was very low.  The background solar
x-ray flux increased from below A-class to approximately A6 during
the past 24 hours and a bright emerging flux region has rotated onto
the east limb.  However, no sunspots are visible in this region yet.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.  There is a slight chance for a C-class flare from the east
limb.
IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z:
The geomagnetic field was quiet.  Solar wind speed remains slightly
elevated at approximately 440 km/s.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet for the next three days (25 - 27 April).
