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

At 05:31:43 UT on 11 Nov 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241111A (trigger 752995908.077622 / 241111230).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 127.1, Dec = -69.3 (J2000 degrees, equivalent to J2000 08h 28m, -69d 17'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 1.0 degrees.
