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

At 01:12:22 UT on 26 Nov 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231126A (trigger 722653947.93232 / 231126050).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 277.4, Dec = 25.6 (J2000 degrees, equivalent to J2000 18h 29m, 25d 36'), with a statistical uncertainty of 6.7 degrees.

The angle from the Fermi LAT boresight is 91.0 degrees.
