Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 361 Issued at 2200Z on 27 Dec 2006
IA.  Analysis of Solar Active Regions and Activity from  26/2100Z
to 27/2100Z:  Solar activity was very low.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 26/2100Z to 27/2100Z:
