GRB Location Alert
GRB 201222B: BALROG localization (Fermi Trigger / GRB 201222461)
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
at 11:03:25 on 22 Dec. 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) = 99.7+/-3.0 deg
Decl.(2000.0) = 27.7+/-4.7 deg
We estimate an additional systematic error of 1 deg.
