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.
