Abstract

Last month in these pages we wrote, “Gamma-ray astronomers expect that [the 28 February gamma-ray burst] is but the first of many GRBs that will soon be revealing much more of themselves…” (page 17). “Soon” turned out to be an understatement. On 8 May, just as we were going to press, the new Italian-Dutch BeppoSAX satellite recorded another GRB, one that will surely make its way into the textbooks.
