Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 121 Issued at 2200Z on 30 Apr 2008
IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 30/2100Z:  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 29/2100Z to 30/2100Z:
The geomagnetic field was quiet to unsettled. 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 with isolated active periods for
the next three days (01-03 May). Elevated activity expected on day
one is in response to the CME observed on 26 April. Activity on days
two and three is in response to a recurrent coronal hole high speed
stream that is expected to rotate into a geoeffective position.
