numerous B-class flares throughout the period and was the only
active region with sunspots this period. No Earth-directed CMEs were
No proton events were observed at geosynchronous orbit.

moderate levels on 16 Apr and high levels on 10-15 Apr with a peak
flux of 3,860 pfu observed at 1715 UTC on 10 Apr.
Geomagnetic field activity was at quiet levels on 10, 13, and 16
