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

At 06:40:59 UT on 12 Dec 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221212A (trigger 692520064.300078 / 221212278).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 142.9, Dec = -19.2 (J2000 degrees, equivalent to J2000 09h 31m, -19d 11'), with a statistical uncertainty of 15.8 degrees.

The angle from the Fermi LAT boresight is 48.0 degrees.
