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

At 06:14:18 UT on 2 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241002B (trigger 749542463.76265 / 241002260).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 333.8, Dec = -64.3 (J2000 degrees, equivalent to J2000 22h 15m, -64d 17'), with a statistical uncertainty of 3.7 degrees.

The angle from the Fermi LAT boresight is 124.0 degrees.
