GRB Location Alert
GRB 200412A: BALROG localization (Fermi Trigger 608367436 / GRB 200412290)
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
608367436 at 06:57:11 on 12 April 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) = 134.2+/-0.8 deg
Decl.(2000.0) = -38.2+/-1.1 deg
We estimate an additional systematic error of 2 deg.
