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

             Solar activity was very low. Region 953 (S10E36) has
       not changed much in area and has only managed to produce several
       B-class flares.

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

            The geomagnetic field was at unsettled to minor storm conditions as a
       recurrent coronal hole high speed stream continues to be
       geoeffective. Solar wind speeds at ace are enhanced around 640 km/s.
       The greater than 2 mev electron flux at geosynchronous orbit reached
       high levels today.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be at unsettled to minor storm conditions on 29 april.
       Mostly unsettled conditions are expected on 30 april. Conditions are
       expected to decrease to quiet to unsettled levels by 01 may.
