The Fermi GBM team reports the detection of a likely LONG GRB
At 18:16:28 UT on 11 Jul 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220711B (trigger 679256193.06458 / 220711761).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 267.8, Dec = 31.5 (J2000 degrees, equivalent to J2000 17h 51m, 31d 30'), with a statistical uncertainty of 4.6 degrees.
The angle from the Fermi LAT boresight is 109.0 degrees.
