GRB 240123B: Fermi GBM Final Real-time Localization
Abstract
At 17:48:03 UT on 23 Jan 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240123B (trigger 727724888.218344 / 240123742). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 312.7, Dec = 17.3 (J2000 degrees, equivalent to J2000 20h 50m, 17d 18'), with a statistical uncertainty of 6.9 degrees. The angle from the Fermi LAT boresight is 51.0 degrees.
