Abstract
The three-satellite SIGNE network has observed 26 confirmed gamma-ray bursts in the period September 1978–June 1979. Burst time histories may be used to define several classes of events, with a strong resemblance between events in a given class, but different arrival directions. The spectra of two gamma-ray bursts have been found to evolve from shapes which turn over at low energy during the start of the event, to near power law spectra at the end of the event.
