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

             Solar activity was at very low levels.  The visible
       solar disk remained spotless.

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

            The geomagnetic field was at mostly quiet to unsettled levels.  Solar
       wind speed at the ace spacecraft began the period at around 600
       km/s, and ended the period at approximately 500 km/s.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be at mostly quiet to unsettled levels, with isolated
       active conditions possible on day one (21 february).  On days two
       and three (22 - 23 february) activity levels are expected to decline
       to predominately quiet levels.
