TITLE: GCN CIRCULAR NUMBER: 23957 SUBJECT: Fermi Trigger 574080135 / GRB 190312446: BALROG localization DATE: 19/03/12 13:06:58 GMT FROM: Jochen Greiner at MPS,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 574080135 at 10:42:10 on 12 March 2019 were automatically fitted for spectrum and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427; Berlato et al. 2019, A&A (in press; arXiv:1902.01082)). The best-fit position (1 sigma statistical errors) is: RA(2000.0) = 326.3+/-1.0 deg Decl.(2000.0) = 24.7+/-2.0 deg We estimate an additional systematic error of 2 deg.
