TITLE: GCN CIRCULAR NUMBER: 25178 SUBJECT: GRB 190727B: BALROG localization (Fermi Trigger 585951481 / GRB 190727846) DATE: 19/07/27 22:03:51 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 585951481 at 20:17:56 on 27 July 2019 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) = 128.2+/-0.3 deg Decl.(2000.0) = -12.2+/-0.5 deg We estimate an additional systematic error of 1 deg.
