Description
During a four-month period beginning July 25, 1989, the sun released an unprecedented barrage of seven relativistic solar particle events detectable with ground-based instrumentation. These 'ground-level enhancements' are the first to occur in the present sunspot cycle, and they include the largest event observed since 1956. Several events are distinguished by unusual fine structure in their time profiles, and one event exhibits an extraordinary spikelike feature at event onset. This paper briefly discusses the characteristics of the time profiles. 10 refs
