TITLE: GCN CIRCULAR NUMBER: 35576 SUBJECT: GRB 240118C: Fermi GBM Final Localization DATE: 24/01/19 14:09:25 GMT FROM: rachel.hamburg@ijclab.in2p3.fr V. Sharma (NASA-GSFC/UMBC) and R. Hamburg (CNRS/IN2P3) report on behalf of the Fermi Gamma-ray Burst Monitor Team: At 17:23:23.93 UT on 18 January 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240118C (trigger 727291408/240118725). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 305.33, Dec = -12.39 (J2000 degrees, equivalent to J2000 20h 21m, 12d 23'), with a statistical uncertainty of 1.8 degrees. The angle from the Fermi LAT boresight is 90.00 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240118725/q...
