TITLE: GCN CIRCULAR NUMBER: 23971 SUBJECT: Fermi Trigger 574678842 / GRB 190319375: BALROG localization DATE: 19/03/19 11:18:56 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 574678842 at 09:00:37 on 19 March 2019 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, ApJ (in press; arXiv:1902.01082)). The best-fit position (1 sigma statistical errors) is: RA(2000.0) = 284.2+/-1.5 deg Decl.(2000.0) = -5.5+/-2.2 deg We estimate an additional systematic error of 2 deg.
