GRB Location Alert

GRB 210627B: BALROG localization (Fermi Trigger 646509445/ GRB 210627748)

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 646509445
at 17:57:20 on 27 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) = 230.5+/-2.5 deg
Decl.(2000.0) = -5.9+/-1.5 deg
We estimate an additional systematic error of 2 deg.
