TITLE: GCN CIRCULAR NUMBER: 35263 SUBJECT: GRB 231205A: Fermi GBM Final Real-time Localization DATE: 23/12/05 02:35:45 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 SHORT GRB At 02:25:11 UT on 5 Dec 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231205A (trigger 723435916.407408 / 231205101). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 206.1, Dec = 22.8 (J2000 degrees, equivalent to J2000 13h 44m, 22d 48'), with a statistical uncertainty of 3.1 degrees. The angle from the Fermi LAT boresight is 79.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2023/bn231205101/q...
