TITLE: GCN CIRCULAR NUMBER: 28641 SUBJECT: GRB 201016A: BALROG localization (Fermi Trigger 624500874 / GRB 201016019) DATE: 20/10/16 03:30:21 GMT FROM: Jochen Greiner at MPE,Garching B. Biltzinger, F. Kunzweiler, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 624500874 at 00:27:49 on 16 Oct. 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) = 176.6+/-0.1 deg Decl.(2000.0) = -4.3+/-0.2 deg We estimate an additional systematic error of 1 deg.
