GRB 221107A: Fermi GBM Final Localization
Abstract
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.
