The Fermi GBM team reports the detection of a likely SHORT GRB
"At 12:55:07.15 UT on 06 September 2023, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 230906A (trigger 715697712/230906538).
The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 81.37, Dec = -47.41 (J2000 degrees, equivalent to J2000 05h 25m, -47d 24'),
with a statistical uncertainty of 2.79 degrees.
The angle from the Fermi LAT boresight is 55.0 degrees.
