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

             Solar activity was low. The only flare of the
       past day was a C8/SF at 02/2352Z in Region 7379 (S12W89).
       This is a small, decaying sunspot group now at the west limb.
       Region 7388 (S08W43), which emerged yesterday, is now growing
       rapidly. Penumbra has already formed on both leader and
       trailer spots. New Region 7390 (N12W35) was numbered.

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

            The geomagnetic field was at unsettled to minor storm levels
       at most stations for the past 24 hours. These disturbed
       conditions had a gradual onset with no clear solar source.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be mostly unsettled at middle latitudes and
       active to storm at high latitudes.

                        Major-Severe Storm    15/15/10

            HF propagation conditions were degraded over the high and
       polar latitude paths for the last 24 hours due to periods of
       minor geomagnetic storm activity.  Many middle latitude regions
       reported moderate to occasional strong degradation in
       association with this activity.  This disturbance appears to
       have subsided and is resulting in gradual improvements in HF
       propagation conditions over these higher latitude regions.
       Areas of heaviest degradation were those near and in the
       auroral regions where fading, multipathing, and anomalous
       absorption was strongest.  Conditions are expected to gradually
       improve over the next 72 hours.  Near-normal propagation should
       return by about 06 January.
