TITLE: GCN CIRCULAR NUMBER: 28156 SUBJECT: GRB 200723A: BALROG localization (Fermi Trigger 617214929 / GRB 200723691) DATE: 20/07/23 17:05:27 GMT FROM: Jochen Greiner at MPE,Garching F. Kunzweiler, B. Biltzinger, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 617214929 at 16:35:24 on 23 July 2020 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, ApJ 873, 60). The best-fit position (1 sigma statistical errors) is: RA(2000.0) = 233.5+/-8.3 deg Decl.(2000.0) = 61.0+/-2.7 deg We estimate an additional systematic error of 2 deg.
