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

             Solar activity increased to low levels.  Newly numbered
       region 953 (S14E73) has partially rotated into view during the
       period and produced a C2 x-ray flare at 25/2256Z.  A four spot hsx
       alpha sunspot group is currently visible in white light.

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

            The geomagnetic field was at quiet to unsettled levels.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be at quiet to unsettled levels on 26 and 27 april.  A
       recurrent coronal hole high speed stream is expected to become
       geoeffective on 29 april.  Active to minor storm conditions are
       expected with the onset of the coronal hole.
