TITLE: GCN CIRCULAR NUMBER: 36015 SUBJECT: GRB 240403A: BALROG localization (Fermi Trigger 733838255 / GRB 240403498) DATE: 24/04/03 15:15:04 GMT FROM: Jochen Greiner at MPE <jcgrog@mpe.mpg.de> 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 733838255 at 11:57:30 on 03 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) = 9.0 deg Decl.(2000.0) = -17.6 deg The 1 sigma statistical error radius is 0.8 deg. We estimate an additional systematic error of 1 deg.
