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

             Solar activity was very low during the past 24 hours.
       Region 953 (S10E49) produced several B-class events during the past
       24 hours. As the region has rotated more fully into view, it now
       appears that the group consists mostly of a large penumbral area
       which contains opposite magnetic polarities, making the group a
       beta-delta magnetic classification.

            Solar activity forecast:  solar activity is expected to be very
       low to low for the next three days (28-30 april), with a slight
       chance for an isolated M-class event from region 953.

            The geomagnetic field was quiet to active during the past 24 hours.
       An initially quiet to unsettled field became unsettled to active
       with the onset of a high speed solar wind stream around 1500Z. Solar
       wind velocity increased to about 600 km/s and the interplanetary
       magnetic field showed fluctuations from about -9 nt to +7 nt.

            Geophysical activity forecast:  the geomagnetic field is
       expected to be mostly active with a chance for isolated minor storm
       periods for the next 24 hours (28 april) as the high speed stream is
       expected to continue. Unsettled levels with a chance for active
       periods is expected for the second day (29 april) and conditions
       should decline to mostly unsettled by the third day (30 april).
