The Fermi GBM team reports the detection of a likely LONG GRB

At 01:23:27 UT on 4 Aug 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190804A (trigger 586574612.354622 / 190804058).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 108.0, Dec = -64.9 (J2000 degrees, equivalent to J2000 07h 12m, -64d 54'), with a statistical uncertainty of 12.0 degrees.

The angle from the Fermi LAT boresight is 117.0 degrees.
