TITLE: GCN CIRCULAR NUMBER: 36047 SUBJECT: GRB 240407A: BALROG localization (Fermi Trigger 734144396 / GRB 240407042) DATE: 24/04/07 10:10:49 GMT FROM: Jochen Greiner at MPE T. Preis, B. Biltzinger, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 734144396 at 00:59:51 on 07 April 2024 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 is: RA(2000.0) = 347.0 deg Decl.(2000.0) = 43.9 deg The 1 sigma statistical error radius is 1.9 deg. We estimate an additional systematic error of 1 deg.
