Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 122 Issued at 2200Z on 01 May 2008
IA.  Analysis of Solar Active Regions and Activity from  30/2100Z
to 01/2100Z:  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.
IIA.  Geophysical Activity Summary 30/2100Z to 01/2100Z:
The geomagnetic field was quiet. 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 be quiet to unsettled on day one (02 May ). Quiet to
unsettled conditions with isolated active periods are expected on
days two and three (03-04 May), with isolated minor storm conditions
possible at high latitudes, due to a recurrent coronal hole high
speed stream.
