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

At 08:12:32 UT on 12 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230112A (trigger 695203957.49759 / 230112342).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 62.4, Dec = -3.4 (J2000 degrees, equivalent to J2000 04h 09m, -3d 23'), with a statistical uncertainty of 15.2 degrees.

The angle from the Fermi LAT boresight is 65.0 degrees.
