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

At 22:41:06 UT on 19 Jan 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250119C (trigger 759019271.302184 / 250119945).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 163.9, Dec = 15.1 (J2000 degrees, equivalent to J2000 10h 55m, 15d 05'), with a statistical uncertainty of 8.8 degrees.

The angle from the Fermi LAT boresight is 66.0 degrees.
