TITLE: GCN CIRCULAR NUMBER: 24677 SUBJECT: Fermi Trigger 580904353 / GRB 190530430 / GRB190530A: BALROG localization DATE: 19/05/30 10:54:24 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 580904353 at 10:19:08 on 30 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) = 120.7+/-0.3 deg Decl.(2000.0) = 36.1+/-0.2 deg We estimate an additional systematic error of 1 deg.
