Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 132 Issued at 2200Z on 11 May 2008
IA.  Analysis of Solar Active Regions and Activity from  10/2100Z
to 11/2100Z:  Solar activity was very low.  The visible solar disk
remains spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 10/2100Z to 11/2100Z:
The geomagnetic field was at quiet levels.  The greater than 2 MeV
electron flux at geosynchronous orbit was high.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet on day 1 (12 May).  Quiet to unsettled
conditions with isolated active periods are possible for days 2-3
(13-14 May).  The increase in activity is expected due to a
recurrent coronal hole high speed stream.
