The Fermi GBM team reports the detection of a likely LONG GRB
At 19:50:04 UT on 29 Sep 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240929A (trigger 749332209.094252 / 240929826).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 356.1, Dec = 75.0 (J2000 degrees, equivalent to J2000 23h 44m, 75d 00'), with a statistical uncertainty of 1.4 degrees.
The angle from the Fermi LAT boresight is 108.0 degrees.
