The Fermi GBM team reports the detection of a likely LONG GRB
At 01:43:15 UT on 15 Jul 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230715A (trigger 711078200.940406 / 230715072).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 117.8, Dec = 46.0 (J2000 degrees, equivalent to J2000 07h 51m, 46d 00'), with a statistical uncertainty of 8.1 degrees.
The angle from the Fermi LAT boresight is 78.0 degrees.
