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

             Solar activity was very low.  Region 956 (S01W74) has
       decayed into a plage region without spots.

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

            The geomagnetic field ranged from unsettled to major storming. 
       Extended periods of southward bz starting on 23 may, combined with
       rising solar wind speeds, accounted for the most disturbed periods. 
       Solar wind speed increased to approximately 650 km/s during the
       summary period due to a recurrent coronal hole rotating into a
       geoeffective position.  The greater then 2 mev electron flux at
       geosynchronous orbit reached high levels today.

            Geophysical activity forecast:  the geomagnetic field is
       expected to range from unsettled to major storming over the next
       three days.  Elevated solar wind speeds due to the geoeffective
       coronal hole and transient material from the cme's on 22 and 23 may
       should produce storm periods on 25 - 26 may.  Expect mostly
       unsettled to active conditions on 27 may.
