FROM:    Rachel Dunwoody at UCD  <rachel.dunwoody@ucdconnect.ie>

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

At 01:22:52.46 UT on 7 Nov 2022, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 221107A (trigger 689476977 / 221107058).

The on-ground calculated location, using the Fermi GBM trigger data, is RA
= 146.15, Dec = -45.40 (J2000 degrees, equivalent to J2000 09h 45m, -45d
24'), with a statistical uncertainty of 2.06 degrees.

The angle from the Fermi LAT boresight is 54 degrees.
