The Fermi GBM team reports the detection of a likely LONG GRB
At 23:59:05 UT on 13 Jul 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230713A (trigger 710985550.945368 / 230713999).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 122.8, Dec = 43.3 (J2000 degrees, equivalent to J2000 08h 11m, 43d 17'), with a statistical uncertainty of 5.5 degrees.
The angle from the Fermi LAT boresight is 86.0 degrees.
