report:
The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
706014351 at 11:05:46 on 17 May 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) = 119.1+/-1.9 deg
Decl.(2000.0) = -48.6+/-0.7 deg
We estimate an additional systematic error of 1 deg.
