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

At 22:27:42 UT on 13 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241013B (trigger 750551267.034726 / 241013936).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 148.4, Dec = -32.3 (J2000 degrees, equivalent to J2000 09h 53m, -32d 17'), with a statistical uncertainty of 2.5 degrees.

The angle from the Fermi LAT boresight is 69.0 degrees.
