GRB Location Alert
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
574345067 at 12:17:42 on 15 March 2019 were automatically fitted for spectrum
and sky location with BALROG (Burgess et al. 2018, MNRAS 476, 1427;
Berlato et al. 2019, ApJ (in press; arXiv:1902.01082)).
The best-fit position (1 sigma statistical errors) is:
RA(2000.0) = 146.0+/-1.9 deg
Decl.(2000.0) = -13.8+/-2.5 deg
We estimate an additional systematic error of 0 deg.
