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

             Solar activity was very low. No flares were observed
       during the past 24 hours.

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

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

            Geophysical activity forecast:  the geomagnetic field is
       expected to be quiet to unsettled with isolated active periods for
       the next three days. An increase is expected late on day one (29
       april) or early on day two (30 april) in response to a glancing blow
       from the cme that was observed on 26 april.
