TITLE: GCN CIRCULAR NUMBER: 24414 SUBJECT: Fermi Trigger 578903308 / GRB 190507270 / GRB190507A: BALROG localization DATE: 19/05/07 07:33:13 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 578903308 at 06:28:23 on 07 May 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) = 158.4+/-3.5 deg Decl.(2000.0) = -10.2+/-3.1 deg We estimate an additional systematic error of 2 deg.
