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

             Solar activity continues at very low levels. Region 956
       (N03W60) produced a B5 flare at 23/0732Z. A type ii radio sweep (582
       km/s) accompanied this flare and a cme was obvious on stereo
       imagery. Region 956 continues its slow decay and is now a small beta
       sunspot group.

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

            The geomagnetic field ranged from quiet to major storming. Extended
       periods of southward bz accounted for the most disturbed periods.
       Transient flow from the 19 may cme likely contributed to this
       disturbance.

            Geophysical activity forecast:  the geomagnetic field is
       expected to range from unsettled to major storming over the next
       three days. A recurrent coronal hole high speed stream is rotating
       into a geoeffective position and is expected to produce storm
       periods. Transient material from today's cme and the cme on 22 may
       will likely contribute to the disturbed periods.
