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

At 03:00:01 UT on 10 Sep 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230910A (trigger 716007606.740604 / 230910125).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 57.0, Dec = 45.9 (J2000 degrees, equivalent to J2000 03h 47m, 45d 53'), with a statistical uncertainty of 2.9 degrees.

The angle from the Fermi LAT boresight is 68.0 degrees.
