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

At 18:30:15 UT on 4 Nov 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241104A (trigger 752437820.424838 / 241104771).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 32.4, Dec = 31.8 (J2000 degrees, equivalent to J2000 02h 09m, 31d 48'), with a statistical uncertainty of 2.8 degrees.

The angle from the Fermi LAT boresight is 62.0 degrees.
