TITLE: GCN CIRCULAR NUMBER: 27568 SUBJECT: GRB 200405B: Further Swift-XRT observations DATE: 20/04/13 13:47:26 GMT FROM: Kim Page at U.of Leicester K.L. Page (U. Leicester) reports on behalf of the Swift-XRT team: Swift-XRT has performed a second follow-up observation of the INTEGRAL/SPI-ACS and Swift-BAT GUANO detected possible short burst GRB 200405B (James DeLaunay et al. GCN Circ. 27497), collecting ~1.2 ks of Photon Counting (PC) mode data between T0+550.8 ks and T0+584.0 ks. Of the four uncatalogued X-ray sources reported in GCN 27500 (Sbarufatti et al.), none shows any evidence of fading. We therefore conclude that Swift did not detect the X-ray afterglow of this GRB. This circular is an official product of the Swift-XRT team.
