The Fermi GBM team reports the detection of a likely LONG GRB
At 18:46:20 UT on 7 Jul 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230707B (trigger 710448385.289496 / 230707782).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 28.5, Dec = -41.3 (J2000 degrees, equivalent to J2000 01h 53m, -41d 17'), with a statistical uncertainty of 2.2 degrees.
The angle from the Fermi LAT boresight is 83.0 degrees.
