GRB Location Alert
GRB 230313A: BALROG localization (Fermi Trigger 700400328 / GRB 230313485)
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
700400328 at 11:38:43 on 13 March 2023 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) = 201.0+/-2.1 deg
Decl.(2000.0) = 52.3+/-2.3 deg
We estimate an additional systematic error of 2 deg.
