TITLE: GCN CIRCULAR NUMBER: 39113 SUBJECT: GRB 250201A: BALROG localization (Fermi Trigger 760096791 / GRB 250201417) DATE: 25/02/01 10:53:32 GMT FROM: Jochen Greiner at MPE <jcgrog@mpe.mpg.de> T. Preis (University of Innsbruck) & J. Greiner (MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 760096791 at 09:59:46 on 01 Feb. 2025 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) = 112.5 deg Decl.(2000.0) = -54.7 deg The 1 sigma statistical error radius is 2.0 deg. We estimate an additional systematic error of 1 deg.
