TITLE: GCN CIRCULAR NUMBER: 27580 SUBJECT: GRB 200415A: BALROG localization (Fermi Trigger 608633290 / GRB 200415367) DATE: 20/04/15 09:11:15 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 608633290 at 08:48:05 on 15 April 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) = 10.8+/-6.4 deg Decl.(2000.0) = -26.3+/-4.7 deg We estimate an additional systematic error of 1 deg.
