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

             Solar activity was very low.  Region 952 (S08W73) was
       numbered today.

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

            The geomagnetic field was quiet to unsettled.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be predominantly quiet to unsettled for the next three
       days (18-20 april).  Isolated active periods are expected on 19-20
       april, with a chance for isolated minor storm conditions at high
       latitudes on 20 april, due to a favorably positioned coronal hole.
