TITLE: GCN CIRCULAR NUMBER: 28834 SUBJECT: GRB 201104A: BALROG localization (Fermi Trigger 626140861 / GRB 201104001) DATE: 20/11/04 22:35:07 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 626140861 at 00:00:56 on 04 Nov. 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) = 67.9+/-10.4 deg Decl.(2000.0) = -73.2+/-1.6 deg We estimate an additional systematic error of 2 deg.
