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

At 03:43:31 UT on 19 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240619A (trigger 740461416.003318 / 240619155).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 162.1, Dec = 17.3 (J2000 degrees, equivalent to J2000 10h 48m, 17d 18'), with a statistical uncertainty of 1.6 degrees.

The angle from the Fermi LAT boresight is 63.0 degrees.
