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

             Solar activity remained at low levels.  Region 958
       (S13E35) continues to decay.  A C1 x-ray flare occurred at 31/1253Z,
       and appeared to have come from a source region just beyond the east
       limb.  No new regions were numbered today.

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

            The geomagnetic field was at quiet levels.  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 at predominantly quiet levels on 01 and 02 june.  A
       recurrent coronal hole high speed stream is expected to become
       geoeffective on 03 june.  Active conditions are possible with the
       onset of the coronal hole.
