The Fermi GBM team reports the detection of a likely LONG GRB
At 12:10:10 UT on 20 Jun 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190620A (trigger 582725415.808842 / 190620507).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 162.1, Dec = 30.5 (J2000 degrees, equivalent to J2000 10h 48m, 30d 30'), with a statistical uncertainty of 1.2 degrees.
The angle from the Fermi LAT boresight is 59.0 degrees.

The public trigdat data of the Fermi Gamma-ray Burst Monitor (GBM) trigger
582725415 at 12:10:10 on 20 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) = 161.2+/-0.7 deg
Decl.(2000.0) = 29.8+/-0.6 deg
We estimate an additional systematic error of 2 deg.
