The Fermi GBM team reports the detection of a likely LONG GRB
At 19:38:18 UT on 30 Jul 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240730B (trigger 744061103.370314 / 240730818).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 202.2, Dec = 23.2 (J2000 degrees, equivalent to J2000 13h 28m, 23d 11'), with a statistical uncertainty of 1.0 degrees.
The angle from the Fermi LAT boresight is 130.0 degrees.
