Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 150 Issued at 2200Z on 29 May 2008
IA.  Analysis of Solar Active Regions and Activity from  28/2100Z
to 29/2100Z:  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 28/2100Z to 29/2100Z:
The geomagnetic field was at mostly quiet levels.  Solar wind
velocities began the summary period at about 550 km/s, but by
29/0200Z had decayed slightly, however still remained elevated
between 450 - 500 km/s.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be at quiet to unsettled levels, with a chance for
isolated active periods, during all three days of the forecast
period (30 May - 01 Jun) due to the high speed stream.
