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

At 01:22:55 UT on 16 Sep 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240916A (trigger 748142580.77199 / 240916058).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 233.2, Dec = -7.1 (J2000 degrees, equivalent to J2000 15h 32m, -7d 05'), with a statistical uncertainty of 1.2 degrees.

The angle from the Fermi LAT boresight is 81.0 degrees.
