TITLE: GCN CIRCULAR NUMBER: 25986 SUBJECT: GRB 191009A: BALROG localization (Fermi Trigger 592297741 / GRB 191009298) DATE: 19/10/09 07:38:41 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 592297741 at 07:08:56 on 09 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) = 30.0+/-5.9 deg Decl.(2000.0) = 67.1+/-2.1 deg We estimate an additional systematic error of 2 deg.
