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

             Solar activity was very low. Spotless plage region 989
       (S11W67) produced an isolated low-level B-class flare. Soho/lasco
       images showed a halo cme, first visible in C2 at 05/1626Z. The cme
       appeared to be from the back side, based on stereo ahead euvi 195
       images and the goes- 10 X-ray signature. No new active regions were
       numbered.

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

            Geomagnetic field activity ranged from quiet to major storm levels
       with a kp = 6 observed during 05/1500 - 1800Z. Ace measurements
       indicated earth entered a fast solar wind flow from a recurrent
       low-latitude coronal hole in the southern hemisphere. Solar wind
       velocities increased during the period with a peak of 671 km/sec
       detected at 05/1634Z. Imf bz reached a minimum of -7 nt at 05/1441Z.
       The greater than 2 mev electron flux at geosynchronous orbit briefly
       reached high levels during the period.

            Geophysical activity forecast:  geomagnetic field activity is
       expected to be at unsettled to minor storm levels on day 1 (06
       april) with major storm levels possible at high latitudes. Activity
       is expected to decrease to unsettled to active levels during days 2
       - 3 (07 - 08 april) as coronal hole effects persist.
