TITLE: GCN CIRCULAR NUMBER: 16691 SUBJECT: GRB 140815A: Swift-XRT observations DATE: 14/08/16 15:16:17 GMT FROM: Angelica Vargas at PSU/Swift V. Mangano (PSU), A. Vargas (PSU) reports on behalf of the Swift-XRT team: We have analysed 2.4 ks of XRT data for the INTEGRAL-detected burst: GRB 140815A, from 19.2 ks to 31.8 ks after the INTEGRAL trigger. The data are entirely in Photon Counting (PC) mode. An X-ray source is detected within the INTEGRAL error circle. Using 2156 s of PC mode data and 2 UVOT images, we find an enhanced XRT position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 86.89221, -8.68015 which is equivalent to: RA (J2000): 05h 47m 34.13s Dec(J2000): -08d 40' 48.5" with an uncertainty of 2.6 arcsec (radius, 90% confidence). This position is 29 arcsec from the INTEGRAL position. We cannot determine at the present time whether the source is fading. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00020406. This circular is an official product of the Swift-XRT team.
