GRB 170519A: Enhanced Swift-XRT position

Using 2439 s of XRT Photon Counting mode data and 5 UVOT images for GRB 170519A, we find an astrometrically corrected X-ray position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 163.42699, +25.37417 which is equivalent to: RA (J2000): 10h 53m 42.48s Dec (J2000): +25d 22' 27.0" with an uncertainty of 1.7 arcsec (radius, 90% confidence). This position may be improved as more data are received. The latest position can be viewed at http://www.swift.ac.uk/xrt_positions. Position enhancement is described by Goad et al. (2007, A&A, 476, 1401) and Evans et al. (2009, MNRAS, 397, 1177). This circular was automatically generated, and is an official product of the Swift-XRT team.
