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

             Solar activity was very low.  New region 991 (S09E29)
       was numbered today and has a bxo-beta configuration spot group.

            Solar activity forecast:  solar activity is expected to remain
       very low.  There is a slight chance of an isolated C-class event
       from region 991.

            The geomagnetic field was quiet.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be mostly quiet on day one (20 april).  A recurrent
       coronal hole high speed stream begins to become geoeffective on day
       two (21 april) with unsettled conditions expected.  Unsettled to
       active levels, with a chance for minor to major storms at high
       latitudes, are anticipated by day three (22 april).
