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

At 23:54:10 UT on 18 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230118A (trigger 695778855.155984 / 230118996).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 330.8, Dec = 20.0 (J2000 degrees, equivalent to J2000 22h 03m, 20d 00'), with a statistical uncertainty of 11.0 degrees.

The angle from the Fermi LAT boresight is 52.0 degrees.
