GRB Location Alert

GRB 191104C: BALROG localization (Fermi Trigger 594557071 / GRB 191104448)

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
594557071 at 10:44:26 on 04 Nov. 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) = 291.3+/-0.8 deg
Decl.(2000.0) = 23.7+/-0.6 deg
We estimate an additional systematic error of 2 deg.
