Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 080 Issued at 2200Z on 20 Mar 2008
IA.  Analysis of Solar Active Regions and Activity from  19/2100Z
to 20/2100Z:  Solar activity was very low.  The visible solar disk
was spotless.
IB.  Solar Activity Forecast:  Solar activity is expected to remain
very low.
IIA.  Geophysical Activity Summary 19/2100Z to 20/2100Z:
The geomagnetic field was quiet to unsettled, with a brief active
period from 12Z-15Z.  The greater than 2 MeV electrons at
geosynchronous orbit reached high levels again today.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be generally quiet for the forecast period.
