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

             Solar activity was very low. No flares were observed in
       the past 24 hours and the solar disk continues to be spotless.

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

            The geomagnetic field was initially quiet to unsettled until about
       0600Z when conditions became disturbed due to the onset of a high
       speed stream from a coronal hole. Activity levels were at active to
       minor storm levels for the remainder of the period.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be mostly unsettled to active on day one (19 august),
       due to the persistent effects from the high speed stream. Quiet to
       unsettled levels are expected on day two (20 august), and quiet
       levels on day three (21 august).
