Gamma-Ray Bursts
Abstract
T. L. Cline, Goddard Space Flight Center, NASA, on behalf of the Ulysses/Compton/PVO Interplanetary Network team for the triangulation of gamma-ray bursts (K. Hurley, M. Sommer, M. Boer, and M. Niel for Ulysses; G. Fishman, C. Kouveliotou, C. Meegan, W. Paciesas, and R. Wilson for Compton/Gamma Ray Observatory; E. Fenimore, R. Klebesadel, and J. Laros for Pioneer/Venus Orbiter; and T. Cline for Ulysses and BATSE), communicates: "We report the source location of the 1992 July 11 event of Earth-crossing time 58157.5 s, its center being at R.A. = 18h47m37s, Decl. = +73 00'.8 (equinox J2000.0), and the elliptical field of maximum likelihood is slanted from R.A. about 282.1 deg, Decl. about +73.1 deg to R.A. about 281.7 deg, Decl. = +72.9 deg. Although the source field will be considerably reduced with the final spacecraft calibration data, the presently determined location is adequately small in extent to warrant the encouragement of follow-up observations at other energies. This is the first of several gamma-ray bursts occurring in mid-July with the potential for precise source location."
