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

At 03:22:51 UT on 7 Jul 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230707A (trigger 710392976.959644 / 230707141).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 173.9, Dec = -17.1 (J2000 degrees, equivalent to J2000 11h 35m, -17d 06'), with a statistical uncertainty of 2.5 degrees.

The angle from the Fermi LAT boresight is 67.0 degrees.
