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

             Solar activity has been very low.  The visible disk is
       spotless.  A slow moving cme was observed in lasco imagery off of
       the west limb and accompanied by a B1 flare at 26/1644Z.

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

            The geomagnetic field ranged from quiet to active.  The greater than
       2Mev electron flux at geosynchronous orbit reached high levels again
       today.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be unsettled to active on 27 may and quiet to unsettled
       on 28 may.  Conditions are expected to abate to quiet on 29 may as
       the recurrent coronal hole high speed stream rotates past its
       geoeffective position.  The cme observed today from the west limb is
       not expected to be geoeffective.
