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

At 08:07:04 UT on 5 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240605B (trigger 739267629.47752 / 240605338).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 68.2, Dec = 34.5 (J2000 degrees, equivalent to J2000 04h 32m, 34d 30'), with a statistical uncertainty of 18.1 degrees.

The angle from the Fermi LAT boresight is 78.0 degrees.
