TITLE: GCN CIRCULAR NUMBER: 29382 SUBJECT: GRB 210202A: BALROG localization (Fermi Trigger / GRB 210202841) DATE: 21/02/02 21:25:11 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 at 20:10:31 on 02 Feb. 2021 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) = 223.5+/-1.5 deg Decl.(2000.0) = -35.5+/-1.0 deg We estimate an additional systematic error of 2 deg.
