The unique cosmic event of 1979 March 5
Abstract
A transient that appears to be neither a typical gamma ray burst nor an X-ray burster was found to possess a variety of unusual properties that would seem to be mutually inconsistent. The observed parameters include a 200 microsecond onset time, a subsequent temporal intensity oscillation with an 0 second period, a spectral feature consistent with a moderately red shifted positron annihilation line, a maximum photon flux greater than any known gamma ray or x ray transient, and a very accurate source location measurement consistent with that of the N49 supernova remnant associated with the large Magellanic Cloud at 55 kpc distance.
