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

"At 23:58:47.92 UT on 02 August 2023, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 230802B (trigger 712713532/230802999).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 22.22, Dec = 9.62 (J2000 degrees, equivalent to J2000 1h 28m, +9d 37'),
with a statistical uncertainty of 5.88 degrees.

The angle from the Fermi LAT boresight is 77 degrees.
