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

At 19:19:45 UT on 24 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240624B (trigger 740949590.263268 / 240624805).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 237.4, Dec = -7.3 (J2000 degrees, equivalent to J2000 15h 49m, -7d 17'), with a statistical uncertainty of 4.3 degrees.

The angle from the Fermi LAT boresight is 58.0 degrees.
