TITLE: GCN CIRCULAR NUMBER: 24774 SUBJECT: GRB190609A: BALROG localization (Fermi Trigger 581758450 / GRB 190609315) DATE: 19/06/09 08:06:38 GMT FROM: Jochen Greiner at MPE,Garching J. Burgess, B. Biltzinger, F. Kunzweiler, F. Berlato & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 581758450 at 07:34:05 on 09 June 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) = 177.6+/-6.9 deg Decl.(2000.0) = -46.4+/-3.9 deg We estimate an additional systematic error of 2 deg.
