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

At 02:49:08 UT on 17 Jul 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230717A (trigger 711254953.822542 / 230717117).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 106.8, Dec = 21.4 (J2000 degrees, equivalent to J2000 07h 07m, 21d 23'), with a statistical uncertainty of 11.3 degrees.

The angle from the Fermi LAT boresight is 64.0 degrees.
