GRB Location Alert

GRB 210104A: BALROG localization (Fermi Trigger 631452424 / GRB 210104477)

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
631452424 at 11:26:59 on 04 Jan. 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) = 102.7+/-5.4 deg
Decl.(2000.0) = 69.8+/-1.3 deg
We estimate an additional systematic error of 1 deg.
