TITLE: GCN CIRCULAR NUMBER: 27546 SUBJECT: GRB 200412A: BALROG localization (Fermi Trigger 608367436 / GRB 200412290) DATE: 20/04/12 07:23:34 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 608367436 at 06:57:11 on 12 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) = 134.2+/-0.8 deg Decl.(2000.0) = -38.2+/-1.1 deg We estimate an additional systematic error of 2 deg.
