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

"At 17:02:38.47 UT on 31 August 2024, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 240831B (trigger 746816563/240831710).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 284.49, Dec = 47.35 (J2000 degrees, equivalent to J2000 18h 58m, +47d 21'),
with a statistical uncertainty of 16.75 degrees.

The angle from the Fermi LAT boresight is 18 degrees.
