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

At 23:17:13 UT on 19 Oct 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 191019B (trigger 593219838.347392 / 191019970).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 216.3, Dec = -40.6 (J2000 degrees, equivalent to J2000 14h 25m, -40d 36'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 82.0 degrees.
