Possible Association of a Hard X-Ray Source with a Cosmic Gamma-Ray Burst

A possible association is noted among a hard X-ray burst detected by OSO-6, a gamma burst detected at the same time by the Vela satellites, and a hard X-ray source observed with balloon-borne X-ray telescopes. Since the X-ray event was located in an error box containing the Vela cone of positions, four Uhuru X-ray sources, and the position box of the hard X-ray source TX 1330+32, these positions are compared. Candidates for the source of the bursts are reduced to TX 1330+32 and 3U 1349+24, which may be the same source. The X-ray spectra of TX 1330+32 and the OSO-6 burst are compared and found to be similar. It is tentatively concluded that TX 1330+32 may be the source of the detected X-ray and gamma bursts.
