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

             Solar activity was low. Several C-class subflares
       occurred, all of which originated from either Region 7360
       (S17E05) or Region 7362 (S04W10). Both Regions showed gradual
       growth during the period. Newly assigned Region 7366 (S12E56)
       displayed gradual growth as well, but produced no flares.

            Solar activity forecast:  solar activity is expected to be
       mostly low. Regions 7360 and 7362 are expected to produce
       C-class subflares. Both Regions also pose a slight threat for
       producing an isolated M-class flare.

            The geomagnetic field has been at quiet to unsettled levels
       for the past 24 hours.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be mostly unsettled during the first two days
       declining slightly to quiet to unsettled levels during the
       final day. However, isolated periods of active conditions may
       occur at high latitudes, particularly during local nighttimes.

            HF propagation conditions continued near-normal throughout the
       last 24 hours.  Similar conditions are expected to persist for the
       next two to three days.  No significant changes are expected.
