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

At 19:33:33 UT on 22 Oct 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221022A (trigger 688160018.552146 / 221022815).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 126.6, Dec = -17.7 (J2000 degrees, equivalent to J2000 08h 26m, -17d 41'), with a statistical uncertainty of 11.4 degrees.

The angle from the Fermi LAT boresight is 116.0 degrees.
