GRB Location Alert
GRB 210704A: BALROG localization (Fermi Trigger 647120009 / GRB 210704815)
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
647120009 at 19:33:24 on 04 July 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) = 158.1+/-1.2 deg
Decl.(2000.0) = 58.3+/-0.5 deg
We estimate an additional systematic error of 1 deg.
