TITLE: GCN CIRCULAR NUMBER: 16348 SUBJECT: GRB 140523A: further Swift-XRT observations DATE: 14/06/02 20:59:57 GMT FROM: Valerio D'Elia at ASDC V. D'Elia (ASDC) reports on behalf of the Swift-XRT team: We have observed again the field of the Fermi GRB 140523A (von Kienlin and Connaughton, GCN 16321; Vianello et al. GCN 16322), to search for variability of the X-ray afterglow candidates. In the 5 ks of XRT data acquired, starting on 2014-05-31 at 02:33:06 UT (i.e., ~ 8 days after the burst), all X-ray candidates are still detected with no hint of afterglow-like variability behavior. We thus conclude that none of the candidate sources is the X-ray afterglow of GRB 140523A. More details about this analysis can be found on: http://www.swift.ac.uk/xrt_products/TILED_GRB00026
