GCN Circular 27775
J. Gropp (PSU) reports on behalf of the Swift-XRT team: We provide an update on the XRT light curve evolution of the candidate X-ray afterglow of GRB 200517A (GCN Circ. 27750). The XRT light curve now comprises data up to 300 ks from the MAXI trigger (GCN Circs. 27750). There is a firm indication of fading with respect to the first observation as reported previously (GCN Circ 27754), with a decay index of 1.04 (+0.21, -0.18). We thus confirm that this is indeed the afterglow of GRB 200517A. The latest results can be viewed via: https://www.swift.ac.uk/xrt_curves/00020993/ This circular is an official product of the Swift-XRT team.
