TITLE: GCN CIRCULAR NUMBER: 13496 SUBJECT: GRB 120716A: Swift-XRT detection DATE: 12/07/19 19:15:34 GMT FROM: Valerio D'Elia at ASDC V. D'Elia (ASDC), J. Gelbord and J. Kennea (PSU) report on behalf of the Swift-XRT team: Swift began a target of opportunity observation of GRB120716A on July 19, 2012 at 14:22 UT, approximately 2.9 days after the discovery (Hurley et al. GCN 13487). Swift data for these observations utilize Target ID 20225. Preliminary analysis of the 1.5 ks downlinked XRT data finds an uncatalogued X-ray source at RA, Dec = 313.05050, 9.59850 which is equivalent to: RA(J2000) =  20h 52m 12.12s Dec(J2000)= +09d 35m 54.6s, with an error radius of 3.4 arcsecs (position enhanced by UVOT field astrometry). The above position is consistent with the optical afterglow detection reported by Cenko et al. (GCN 13489), Xu et al. (GCN 13490), Schady et al. (GCN 13492). In addition, no known X-ray object is present at the XRT coordinates, so this is likely the X-ray afterglow of GRB120716A. The count rate of the XRT source is 8.32E-03+/-2.9E-03 cts/s. We cannot determine at the present time whether the source is fading. This circular is an official product of the Swift-XRT team. ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
