TITLE: GCN CIRCULAR NUMBER: 15404 SUBJECT: GRB 131029A: Swift-XRT follow up DATE: 13/10/30 21:59:13 GMT FROM: Phil Evans at U of Leicester P.A. Evans (U. Leicester), J.P. Osborne (U. Leicester), J.L. Racusin (NASA/GSFC) report on behalf of the Swift-XRT team The Swift-XRT has observed the vicinity of GRB 131029A (Racusin et al., GCN 15399); gathering 600-900 s on each of 7 tiled pointings (see Evans, GCN Circ. 15400), covering the entire LAT 90% error circle. No credible X-ray afterglow has been found: we find three sub-threshold (i.e. low significance) detections, 2 of which are near to catalogued X-ray sources and the other is near to an object in SIMBAD. The 3-sigma XRT upper limit for the field is approximately 0.01 ct/sec. This circular is an official product of the Swift-XRT team.
