The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
579814215 at 19:30:10 on 17 May 2019 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) = 270.6+/-1.6 deg
Decl.(2000.0) = 20.3+/-1.0 deg
We estimate an additional systematic error of 2 deg.

The Fermi GBM team reports the detection of a likely LONG GRB
At 19:30:10 UT on 17 May 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190517A (trigger 579814215.17247 / 190517813).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 270.0, Dec = 25.8 (J2000 degrees, equivalent to J2000 18h 00m, 25d 48'), with a statistical uncertainty of 1.2 degrees.
The angle from the Fermi LAT boresight is 79.0 degrees.
