GRB Location Alert

GRB 201121A: BALROG localization (Fermi Trigger 627614994 / GRB 201121062)

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
627614994 at 01:29:49 on 21 Nov. 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) = 212.11+/-1.14 deg
Decl.(2000.0) = -25.44+/-1.07 deg
We estimate an additional systematic error of 1 deg.
