TITLE: GCN CIRCULAR NUMBER: 35664 SUBJECT: GRB 240204A: Fermi GBM Final Real-time Localization DATE: 24/02/04 15:18:07 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM <do_not_reply@GIOC.nsstc.nasa.gov> The Fermi GBM team reports the detection of a likely LONG GRB At 15:07:38 UT on 4 Feb 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240204A (trigger 728752063.677018 / 240204630). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 101.5, Dec = -3.4 (J2000 degrees, equivalent to J2000 06h 46m, -3d 23'), with a statistical uncertainty of 1.6 degrees. The angle from the Fermi LAT boresight is 102.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240204630/q...
