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

             Solar activity was very low. Region 990 (N27W03)
       produced a low level B-class flare at 0634Z. This region has decayed
       to spotless plage.

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

            The geomagnetic field was mostly quiet to unsettled with an isolated
       active period between 0600 - 0900Z. The greater than 2 mev electron
       flux at geosynchronous orbit reached high levels during the past 24
       hours.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be quiet.
