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

At 18:06:20 UT on 11 May 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240511A (trigger 737143585.263482 / 240511754).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 336.8, Dec = 3.8 (J2000 degrees, equivalent to J2000 22h 27m, 3d 47'), with a statistical uncertainty of 3.6 degrees.

The angle from the Fermi LAT boresight is 49.0 degrees.
