TITLE: GCN CIRCULAR NUMBER: 35293 SUBJECT: GRB 231206B: Fermi GBM Final Real-time Localization DATE: 23/12/06 19:07:09 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 18:56:37 UT on 6 Dec 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231206B (trigger 723581802.598578 / 231206789). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 41.9, Dec = 3.9 (J2000 degrees, equivalent to J2000 02h 47m, 3d 53'), with a statistical uncertainty of 8.3 degrees. The angle from the Fermi LAT boresight is 108.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2023/bn231206789/q...
