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

             Solar activity was very low. Region 953 (S10E23) has
       shown a slight decrease in trailing spots bordering the main spot.
       Also, the beginnings of a possible separation of penumbral area on
       the eastern side of the main spot was noted.

            Solar activity forecast:  solar activity is expected to be very
       low to low with a chance for an M-flare from region 953.

            The geomagnetic field was at quiet to minor storm conditions.
       Increased activity was due to the continued influence of a recurrent
       coronal hole high speed stream. The greater than 2 mev electron flux
       at geosynchronous orbit reached high levels again today.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be quiet to active with isolated minor storm periods
       possible on 30 april. Activity is expected to decrease to quiet to
       unsettled levels by 01 and 02 may.
