GRB 231109A: Fermi GBM Final Localization
Abstract
At 06:34:01.34 UT on 9 Nov 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231109A (trigger 721204446 / 231109274). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 173.0, Dec = 50.7 (J2000 degrees, equivalent to J2000 11h 32m, 50d 42'), with a statistical uncertainty of 6.8 degrees. The angle from the Fermi LAT boresight is 143 degrees.
