GRB Location Alert

GRB 200722A: BALROG localization (Fermi Trigger 617076900 / GRB 200722094)

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
617076900 at 02:14:55 on 22 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) = 187.5+/-1.5 deg
Decl.(2000.0) = 4.7+/-1.3 deg
We estimate an additional systematic error of 2 deg.
