TITLE: GCN CIRCULAR NUMBER: 35855 SUBJECT: GRB 240303C: BALROG localization (Fermi Trigger 731189113 / GRB 240303837) DATE: 24/03/03 20:55:32 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 731189113 at 20:05:08 on 03 March 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) = 324.2 deg Decl.(2000.0) = -49.0 deg The 1 sigma statistical error radius is 3.0 deg. We estimate an additional systematic error of 1 deg.
