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

At 10:51:19 UT on 11 Oct 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 221011A (trigger 687178284.149696 / 221011452).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 196.4, Dec = 0.6 (J2000 degrees, equivalent to J2000 13h 05m, 0d 36'), with a statistical uncertainty of 1.0 degrees.

The angle from the Fermi LAT boresight is 74.0 degrees.
