Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 360 Issued at 2200Z on 26 Dec 2006
IA.  Analysis of Solar Active Regions and Activity from  25/2100Z
to 26/2100Z:  Solar activity was very low.  No new regions were
numbered today.
IB.  Solar Activity Forecast:  Solar activity is expected to be very
low.
IIA.  Geophysical Activity Summary 25/2100Z to 26/2100Z:
The geomagnetic field was at quiet levels.  The greater than 2 MeV
electron flux at geosynchronous orbit was at high levels.
IIB.  Geophysical Activity Forecast:  The geomagnetic field is
expected to be quiet to unsettled with isolated active conditions
for 27 December due to a recurrent solar sector boundary crossing. 
Predominately quiet conditions are expected for 28-29 December.
