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

At 01:40:02 UT on 19 Oct 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201019A (trigger 624764407.642026 / 201019069).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 223.8, Dec = -25.0 (J2000 degrees, equivalent to J2000 14h 55m, -25d 00'), with a statistical uncertainty of 2.3 degrees.

The angle from the Fermi LAT boresight is 89.0 degrees.
