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

             Solar activity was low with several C-class flares
       observed.  New Region 7623 (S11E67) rotated onto the disk and
       produced a C2/SF flare at 26/1605Z.  Region 7620 (N04W40)
       produced a C1 flare at 26/1712Z.  All regions appear to be
       stable.

            Solar activity forecast:  solar activity is expected to be
       at low levels during the period.

       STD: The latest Yohkoh image has been appended to this report.

            The geomagnetic field has been at quiet levels for
       the past 24 hours.  High latitudes reported isolated
       undettled levels during the period.

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

            HF propagation conditions were normal over all regions.
       No changes are expected over the next three days, through 29
       November inclusive.  Normal propagation should persist over all
       regions.

NOTES:
     All times are in Universal Time (UT).  Characters preceding begin, max,
     and end times are defined as:  B = Before,  U = Uncertain,  A = After.
     All times associated with x-ray flares (ex. flares which produce
     associated x-ray bursts) refer to the begin, max, and end times of the
     x-rays.  Flares which are not associated with x-ray signatures use the
     optical observations to determine the begin, max, and end times.

     Acronyms used to identify sweeps and optical phenomena include:

          II        = Type II Sweep Frequency Event
          III       = Type III Sweep
          IV        = Type IV Sweep
          V         = Type V Sweep
          Continuum = Continuum Radio Event
          Loop      = Loop Prominence System,
          Spray     = Limb Spray,
          Surge     = Bright Limb Surge,
          EPL       = Eruptive Prominence on the Limb.
