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

At 23:26:55 UT on 7 Dec 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201207A (trigger 629076420.72719 / 201207977).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 124.1, Dec = -50.5 (J2000 degrees, equivalent to J2000 08h 16m, -50d 30'), with a statistical uncertainty of 2.4 degrees.

The angle from the Fermi LAT boresight is 120.0 degrees.
