GRB Location Alert
GRB 190901A: BALROG localization (Fermi Trigger 589065714 / GRB 190901890)
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
589065714 at 21:21:49 on 01 Sept. 2019 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) = 224.7+/-0.8 deg
Decl.(2000.0) = -0.5+/-1.1 deg
We estimate an additional systematic error of 2 deg.
