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

At 19:32:44 UT on 26 Aug 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230826A (trigger 714771169.528076 / 230826814).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 82.8, Dec = 67.1 (J2000 degrees, equivalent to J2000 05h 31m, 67d 05'), with a statistical uncertainty of 2.0 degrees.

The angle from the Fermi LAT boresight is 117.0 degrees.
