TITLE: GCN CIRCULAR NUMBER: 19359 SUBJECT: GRB 160422A: XRT Afterglow Confirmation DATE: 16/04/28 13:38:27 GMT FROM: Alessandro Maselli at INAF/IASF Palermo A. Maselli (INAF-IASFPA), D. Malesani (DARK/NBI), K.L. Page and P.A. Evans (U. Leicester) report on behalf of the Swift-XRT team: Swift-XRT has conducted further observations of the field of the Fermi-detected burst GRB 160422A (Yassine et al., GCN Circ. 19329; Burns et al., GCN Circ. 19331), extending from T0+400 ks to T0+470 ks after the Fermi/GBM trigger. At the position of the candidate afterglow reported by Maselli et al. (GCN Circ. 19334) no source is detected in the new observation, with a three sigma upper limit of 2.6e-3 ct/s. This confirms that it was the X-ray afterglow of GRB 160422A. The results of the full analysis of the XRT observations are available at http://www.swift.ac.uk/xrt_products/00020605 This circular is an official product of the Swift-XRT team.
