TITLE: GCN CIRCULAR NUMBER: 26880 SUBJECT: GRB 200125B: BALROG localization (Fermi Trigger 601677816 / GRB 200125864) DATE: 20/01/25 21:20:59 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 601677816 at 20:43:31 on 25 Jan. 2020 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) = 7.7+/-0.8 deg Decl.(2000.0) = 64.4+/-0.4 deg We estimate an additional systematic error of 2 deg.
