GRB 210619A: BALROG localization (Fermi Trigger 645799548 / GRB 210619532)

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
645799548 at 12:45:43 on 19 June 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) = 69.9+/-1.8 deg
Decl.(2000.0) = 8.8+/-1.7 deg
We estimate an additional systematic error of 1 deg.
