Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 175 Issued at 2200Z on 23 Jun 2008
IA.  Analysis of Solar Active Regions and Activity from  22/2100Z
to 23/2100Z:  Solar activity was very low. No flares were observed
during the past 24 hours.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low for the next three days (24-26 June).
IIA.  Geophysical Activity Summary 22/2100Z to 23/2100Z:
The geomagnetic field was quiet. The greater than 2 MeV electron flux
at geosynchronous orbit reached high levels during the past 24
hours.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled during the next three days (24-26
June). The increase in activity is forecast due to the expected
arrival of a coronal hole high speed stream.
