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

At 04:14:27 UT on 15 Dec 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221215A (trigger 692770472.974848 / 221215177).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 156.1, Dec = 38.6 (J2000 degrees, equivalent to J2000 10h 24m, 38d 36'), with a statistical uncertainty of 13.6 degrees.

The angle from the Fermi LAT boresight is 45.0 degrees.
