TITLE: GCN CIRCULAR NUMBER: 12440 SUBJECT: GRB 111016A: Swift-XRT observations DATE: 11/10/16 20:49:25 GMT FROM: Phil Evans at U of Leicester J.P. Osborne (U. Leicester), D.N. Burrows (PSU), J.A. Kennea (PSU), G. Cusumano (INAF-IASF PA), M. Perri (ASDC) and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team: The XRT began observing the field of GRB 111016A at 18:40:03.2 UT, 178.7 seconds after the BAT trigger. XRT found a bright, uncatalogued X-ray source located at RA, Dec 153.8334, +27.4634 which is equivalent to: RA(J2000) = 10h 15m 20.01s Dec(J2000) = +27d 27' 48.2" with an uncertainty of 6.0 arcseconds (radius, 90% containment). This location is 98 arcseconds from the BAT onboard position, within the BAT error circle. No event data are yet available to determine the column density using X-ray spectroscopy. The initial flux in the 2.5 s image was 0.00e+00 erg cm^-2 s^-1 (0.2-10 keV).
