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

At 22:00:04 UT on 8 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241008A (trigger 750117609.348226 / 241008917).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 112.9, Dec = -14.5 (J2000 degrees, equivalent to J2000 07h 31m, -14d 30'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 77.0 degrees.
