TITLE: GCN CIRCULAR NUMBER: 27474 SUBJECT: GRB 200402A: BALROG localization (Fermi Trigger 607513182 / GRB 200402403) DATE: 20/04/02 10:20:48 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 607513182 at 09:39:37 on 02 April 2020 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) = 44.0+/-2.4 deg Decl.(2000.0) = 43.7+/-2.3 deg We estimate an additional systematic error of 1 deg.
