TITLE: GCN CIRCULAR NUMBER: 33469 SUBJECT: GRB 230313A: BALROG localization (Fermi Trigger 700400328 / GRB 230313485) DATE: 23/03/13 12:42:40 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 700400328 at 11:38:43 on 13 March 2023 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) = 201.0+/-2.1 deg Decl.(2000.0) = 52.3+/-2.3 deg We estimate an additional systematic error of 2 deg.
