GRB Location Alert

GRB 211216A: BALROG localization (Fermi Trigger 661329957 / GRB 211216282)

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
661329957 at 06:45:52 on 16 Dec. 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) = 51.0+/-2.4 deg
Decl.(2000.0) = -62.2+/-4.0 deg
We estimate an additional systematic error of 2 deg.
