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

             Solar activity was very low. No flares occurred during
       the past 24 hours. New region 992 (N13W01) emerged today as a small,
       C-type sunspot group.

            Solar activity forecast:  solar activity is expected to be very
       low for the next three days (23-25 april).

            The geomagnetic field was quiet from the beginning of the period
       through about 1500Z. Since then activity has been unsettled.
       Real-time solar wind data from ace indicate a possible solar sector
       boundary from 'away' orientation (positive) to 'towards' orientation
       (negative) at about 1410Z.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be mostly unsettled with a chance for isolated active
       periods for the first and second days (23-24 april). The elevated
       activity is expected in response to a coronal hole which should be
       in a favorable position on those days. Activity is expected to
       decline to quiet to unsettled for the third day (25 april).
