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

At 14:45:31 UT on 7 Jan 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220107A (trigger 663259536.927164 / 220107615).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 168.2, Dec = 35.0 (J2000 degrees, equivalent to J2000 11h 12m, 35d 00'), with a statistical uncertainty of 1.2 degrees.

The angle from the Fermi LAT boresight is 77.0 degrees.
