Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 151 Issued at 2200Z on 30 May 2008
IA.  Analysis of Solar Active Regions and Activity from  29/2100Z
to 30/2100Z:  Solar activity was at very low levels.  The visible
disk remained spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
at very low levels.
IIA.  Geophysical Activity Summary 29/2100Z to 30/2100Z:
The geomagnetic field was at quiet to unsettled levels.  Solar wind
velocities peaked at 665 km/s at about 30/0400Z, and remained
elevated between 550 - 600 km/s for the balance of the period.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled levels, with a chance for
isolated active periods, during days one and two (31 May - 01 Jun). 
By day three (02 Jun), the geomagnetic field is expected to return
to mostly quiet levels.
