New X-Ray Transient Repeater
Abstract
K. Hurley, on behalf of the Ulysses Gamma-Ray Burst Team; C. Kouveliotou, A. Harmon, G. Fishman, and M. Briggs, on behalf of the BATSE/GRO team; J. van Paradijs, University of Amsterdam; and J. Kommers and W. Lewin, Massachusetts Institute of Technology, report: "A preliminary network synthesis position (cf. Hurley 1994, Ap.J. 431, L31) for the new repeating x-ray transient source (IAUC 6272) has been obtained using Ulysses and BATSE (specifically, 59 BATSE events from Dec. 2). The position is an annulus whose half-width is 0.21 deg centered at R.A. = 2h44m37s, Decl. = -55o31'.0 (equinox 2000.0), with central radius 87.500 deg. Using the BATSE occultation technique, we excluded a large area of the sky for the source origin. The intersection of the network synthesis annulus with the remaining (allowed) area of detection may be approximated by a box with the following coordinates: R.A. = 17h50m, Decl. = -28o.1; 17h49m, -28o.5; 17h23m, -30o.3; 17h19m, -31o.0."
