The Fermi GBM team reports the detection of a likely SHORT GRB
At 04:27:16 UT on 5 Sep 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240905B (trigger 747203241.139826 / 240905186).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 266.1, Dec = 16.9 (J2000 degrees, equivalent to J2000 17h 44m, 16d 53'), with a statistical uncertainty of 1.0 degrees.
The angle from the Fermi LAT boresight is 25.0 degrees.
