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

At 05:53:58 UT on 20 Nov 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241120A (trigger 753774843.543556 / 241120246).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 192.5, Dec = 49.7 (J2000 degrees, equivalent to J2000 12h 50m, 49d 42'), with a statistical uncertainty of 1.2 degrees.

The angle from the Fermi LAT boresight is 36.0 degrees.
