GRB Location Alert
GRB 210120A: BALROG localization (Fermi Trigger 632819449 / GRB 210120299)
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
632819449 at 07:10:44 on 20 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) = 163.5+/-2.8 deg
Decl.(2000.0) = 17.0+/-2.2 deg
We estimate an additional systematic error of 1 deg.
