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

             Solar activity was at very low levels.  The visible
       solar disk remained spotless.

            Solar activity forecast:  solar activity is expected to remain
       at very low levels.

            The geomagnetic field was at unsettled to active levels due to the
       continued influence of a recurrent coronal hole high speed stream. 
       Solar wind speed at the ace spacecraft reached a maximum of
       approximately 760 km/s at 11/0825Z.  At the end of the summary
       period wind speed had declined to below 680 km/s.  The greater than
       2 mev electron flux at geosynchronous orbit reached high levels
       today.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be at mostly unsettled levels throughout the forecast
       period (12-14 february).  Isolated periods of active conditions at
       middle latitudes and minor storm levels at high latitudes are
       possible all three days, due to continued effects of the high speed
       stream.
