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

             Solar activity was very low.

            Solar activity forecast:  solar activity is expected to be very
       low.

            The geomagnetic field was at unsettled to active conditions due to
       the continued influence of the recurrent coronal hole high speed
       stream.  Solar wind speeds, as measured from the ace spacecraft,
       remain around 600 km/s.  The greater than 2 mev electron flux at
       geosynchronous orbit was at high levels.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be unsettled with isolated active periods for 25 april. 
       Predominantly quiet conditions are expected for 26-27 april.
