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

             Solar activity was very low. Region 988 (S07W35)
       produced today's only B-class flare, a B2/sf at 0534Z. All three
       regions on the disk were quiet and stable and show an overall
       declining trend.

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

            The geomagnetic field was quiet. The greater than 2 mev electron flux
       at geosynchronous orbit was high during the past 24 hours.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be quiet for the next three days (01-03 april).
