A summary of the significant solar-terrestrial events that occurred during the Retrospective World Interval of 20 March - 5 May 1976 has been prepared using data available at the present time. Although this period occurred at solar minimum, it was an active interval--one in which the principal events were associated with solar activity in a region at Carrington Longitude (about 45 degrees). Among the events summarized are the following: (1) solar activity during the period 20-23 March 1976 from a region behind the eastern limb of the sun; (2) a large geomagnetic storm with intense mid-latitude auroral activity of 26 March; (3) moderate solar particle intensities at the Earth from 26 through 31 March; and (4) a ground-level solar cosmic ray event on 30 April having a very hard spectrum. Sixty-seven individual data contributions were received from scientists from many countries after the Study of Traveling Interplanetary Phenomena (STIP) committee made a preliminary evaluation of the activity that occurred during STIP Interval II.
