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

At 01:31:33 UT on 29 Nov 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241129A (trigger 754536698.4246 / 241129064).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 245.5, Dec = 1.1 (J2000 degrees, equivalent to J2000 16h 22m, 1d 06'), with a statistical uncertainty of 5.0 degrees.

The angle from the Fermi LAT boresight is 75.0 degrees.
