TITLE: GCN CIRCULAR NUMBER: 16464 SUBJECT: GRB 140623A: further Swift-XRT observations DATE: 14/06/27 13:41:23 GMT FROM: Valerio D'Elia at ASDC V. D'Elia (ASDC), L. Izzo (URoma/ICRA) report on behalf of the Swift-XRT team: We report further Swift-XRT observations of GRB 140623A (A. von Kienlin, GCN Circ 16450; Bhalerao et al., GCN Circ. 16442). A new exposure of 5 ks has been secured 285 ks after the Fermi/GBM detection. The X-ray counterpart detected by D'Elia et al. (GCN Circ. 16451) is no longer present down to a three sigma upper limit of 2.2E-3 cts/s. We thus conclude that the source reported in D'Elia et al. (GCN Circ. 16451) is the X-ray afterglow of GRB 140623A. This circular is an official product of the Swift-XRT team.
