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

             Solar activity was very low. Spotless plage region 989
       (S11W54) produced isolated B-class subflares. No new regions were
       numbered.

            Solar activity forecast:  solar activity is expected to be very
       low to low. There is a fair chance for an isolated C-class flare
       from region 989.

            Geomagnetic field activity was at quiet to active levels. Field
       activity increased to active levels during 04/1800 - 2100Z due to
       increased solar wind velocities and imf magnitude combined with
       periods of southward imf bz. Ace signatures indicated earth entered
       the co-rotating interaction region between slow and fast solar wind
       flows. Velocities increased to 507 km/sec near the close of the
       summary period. The greater than 2 mev electron flux at
       geosynchronous orbit was high during most of the period.

            Geophysical activity forecast:  geomagnetic field activity is
       expected to be at active levels during days 1 - 2 (05 - 06 april)
       with minor to major storm periods at high latitudes due to coronal
       hole effects. Field activity is expected to decrease to unsettled
       levels on day 3 (07 april) with active to minor storm periods at
       high latitudes as coronal hole effects decrease.
