GRB 231118A: Fermi GBM Final Real-time Localization
Abstract
At 17:16:29 UT on 18 Nov 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231118A (trigger 722020594.832338 / 231118720). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 4.0, Dec = -48.2 (J2000 degrees, equivalent to J2000 00h 16m, -48d 12'), with a statistical uncertainty of 1.4 degrees. The angle from the Fermi LAT boresight is 118.0 degrees.
