The Fermi GBM team reports the detection of a likely LONG GRB
At 08:50:06 UT on 22 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190622A (trigger 582886211.27625 / 190622368).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 165.2, Dec = -53.6 (J2000 degrees, equivalent to J2000 11h 00m, -53d 36'), with a statistical uncertainty of 22.9 degrees.
The angle from the Fermi LAT boresight is 23.0 degrees.

The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
582886211 at 08:50:06 on 22 June 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) = 146.4+/-3.8 deg
Decl.(2000.0) = -41.1+/-3.0 deg
We estimate an additional systematic error of 1 deg.
