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

At 23:08:22 UT on 19 Sep 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200919C (trigger 622249707.644918 / 200919964).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 273.4, Dec = -23.2 (J2000 degrees, equivalent to J2000 18h 13m, -23d 11'), with a statistical uncertainty of 1.2 degrees.

The angle from the Fermi LAT boresight is 69.0 degrees.
