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

At 21:41:52 UT on 2 Dec 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221202B (trigger 691710117.068684 / 221202904).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 346.4, Dec = -3.1 (J2000 degrees, equivalent to J2000 23h 05m, -3d 06'), with a statistical uncertainty of 1.2 degrees.

The angle from the Fermi LAT boresight is 82.0 degrees.
