GRB Location Alert

GRB 210204A: BALROG localization (Fermi Trigger 634112970 / GRB 210204270)

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
634112970 at 06:29:25 on 04 Feb. 2021 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) = 118.6+/-3.1 deg
Decl.(2000.0) = 12.0+/-3.1 deg
We estimate an additional systematic error of 1 deg.
