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

At 20:50:53 UT on 11 Oct 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 241011A (trigger 750372658.888186 / 241011869).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 68.6, Dec = -29.9 (J2000 degrees, equivalent to J2000 04h 34m, -29d 53'), with a statistical uncertainty of 7.0 degrees.

The angle from the Fermi LAT boresight is 73.0 degrees.
