The Fermi GBM team reports the detection of a likely LONG GRB
At 06:50:05 UT on 22 Oct 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191022A (trigger 593419810.073896 / 191022285).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 273.1, Dec = -23.1 (J2000 degrees, equivalent to J2000 18h 12m, -23d 06'), with a statistical uncertainty of 3.2 degrees.
The angle from the Fermi LAT boresight is 36.0 degrees.

The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
593419810 at 06:50:05 on 22 Oct. 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) = 277.1+/-5.2 deg
Decl.(2000.0) = -19.6+/-3.6 deg
We estimate an additional systematic error of 2 deg.
