TITLE: GCN CIRCULAR NUMBER: 25894 SUBJECT: GRB 191001A: BALROG localization (Fermi Trigger 591604915 / GRB 191001279) DATE: 19/10/01 07:00:08 GMT FROM: Jochen Greiner at MPE,Garching J. Burgess , F. Kunzweiler, B. Biltzinger, F. Berlato, & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 591604915 at 06:41:50 on 01 Oct. 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) = 313.4+/-6.0 deg Decl.(2000.0) = 15.1+/-1.4 deg We estimate an additional systematic error of 2 deg.
