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

             Solar activity was very low. Two optically uncorrelated
       B-class X-ray bursts occurred very early in the period. Minor
       growth was noted in Region 7389 (S20W17). The remaining regions
       were stable. New Region 7399 (N07E16) was numbered.

            Solar activity forecast:  solar activity is expected to be
       very low to low. An isolated C-class subflare may occur within
       Region 7386 (S05W38).

            The geomagnetic field has been at mostly unsettled levels for
       the past 24 hours. Active to minor storm levels occurred at
       high latitudes from 09/0900-1800Z and may have been due to
       coronal hole effects.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be mostly unsettled. Active periods may occur
       during the first day due to coronal hole effects.

            HF propagation conditions were near-normal over most
       regions today.  Auroral latitudes and the upper middle
       latitudes experienced minor signal degradations between 06:00
       UT and 12:00 UT due to enhanced geomagnetic and auroral
       activity.  Conditions improved throughout the remainder of the
       day.  All regions should continue to see near-normal
       propagation for the next 72 hours.  Additional minor signal
       degradation may be possible for the next 24 hours on paths
       which cross into or pass near the auroral ovals during the
       local night and morning sectors.  Global improvements in
       night-sector signal stability are expected on 11 or 12 January.
