TITLE: GCN CIRCULAR NUMBER: 26945 SUBJECT: GRB 200130B: BALROG localization (Fermi Trigger 602071201 / GRB 200130417) DATE: 20/01/30 10:35:00 GMT FROM: Jochen Greiner at MPE,Garching F. Kunzweiler, B. Biltzinger, F. Berlato, J. Burgess & J. Greiner (all MPE Garching) report: The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger 602071201 at 09:59:56 on 30 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) = 138.5+/-1.4 deg Decl.(2000.0) = -56.9+/-0.9 deg We estimate an additional systematic error of 2 deg.
