Gamma-burst observations from the Pioneer Venus Orbiter

The LASL Pioneer Venus Orbiter Gamma Burst Detector (OGBD) is a vital element in the long base-line array of similar instruments intended to precisely locate sources of gamma-ray bursts. Results of early observations are described. The source of the gamma-ray burst of 5 March, 1979 (the first to be located with precision) has been determined to be consistent with the direction of supernova remnant N49 within the LMC. Approximate locations defined for a small number of events suggest no departure from an isotropic distribution.
