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

             Solar activity was very low.  No flares were observed
       during the past 24 hours, and the visible disk was spotless.

            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 range from quiet to active for the next three days
       (20-22 april).  Isolated  minor storm conditions are possible at
       high latitudes on 20 april due to a favorably positioned coronal
       hole.
