Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 177 Issued at 2200Z on 26 Jun 2007
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.  Region 961 (S11E60)
remains an Hsx alpha sunspot group.  No significant flare activity
occurred during the last 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low, with a slight chance for C-class flares late in the period.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was quiet to unsettled.  The greater than 2 MeV
electron flux at geosynchronous orbit reached high levels again
today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to range from quiet to unsettled.  Active periods are
possible, particularly at high latitudes, on 29 June.
