The Fermi GBM team reports the detection of a likely LONG GRB
At 03:21:41 UT on 13 Sep 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240913A (trigger 747890506.70684 / 240913140).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 68.7, Dec = 13.8 (J2000 degrees, equivalent to J2000 04h 34m, 13d 48'), with a statistical uncertainty of 6.0 degrees.
The angle from the Fermi LAT boresight is 88.0 degrees.
