SYNOPSIS OF ACTIVITY
--------------------

             Solar activity was at very low levels.

            Solar activity forecast:  solar activity is expected to remain
       at very low levels.

            The geomagnetic field was at quiet to active levels.  These elevated
       conditions were due to a coronal hole high speed stream.  Solar wind
       speed at the ace spacecraft peaked late yesterday between 18/1900Z
       and 19/0100Z with maximum values around 700 km/s.  Since then solar
       wind speed has been steadily declining with values around 600 km/s
       at forecast issue time.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be at predominately quiet to unsettled levels.  However,
       there is a chance for isolated active conditions on 20 and 21
       december, due to the continued influence of the high speed stream.
