TITLE: GCN CIRCULAR NUMBER: 28039 SUBJECT: GRB 200629A: BALROG localization (Fermi Trigger 615127794 / GRB 200629535) DATE: 20/06/29 16:41:06 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 615127794 at 12:49:49 on 29 June 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) = 339.4+/-3.0 deg Decl.(2000.0) = -64.8+/-1.0 deg We estimate an additional systematic error of 1 deg.
