TITLE: GCN CIRCULAR NUMBER: 25751 SUBJECT: GRB 190915A: BALROG localization (Fermi Trigger 590219102 / GRB 190915240) DATE: 19/09/15 06:11:07 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 590219102 at 05:44:57 on 15 Sept. 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) = 54.2+/-4.5 deg Decl.(2000.0) = 7.2+/-3.1 deg We estimate an additional systematic error of 1 deg.
