GRB Location Alert
GRB 200723A: BALROG localization (Fermi Trigger 617214929 / GRB 200723691)
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
617214929 at 16:35:24 on 23 July 2020 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) = 233.5+/-8.3 deg
Decl.(2000.0) = 61.0+/-2.7 deg
We estimate an additional systematic error of 2 deg.
