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

At 02:23:28 UT on 13 Oct 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221013B (trigger 687320613.487128 / 221013100).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 220.8, Dec = -36.3 (J2000 degrees, equivalent to J2000 14h 43m, -36d 17'), with a statistical uncertainty of 14.6 degrees.

The angle from the Fermi LAT boresight is 109.0 degrees.
