TITLE: GCN CIRCULAR NUMBER: 35310 SUBJECT: GRB 231210A: Fermi GBM Final Real-time Localization DATE: 23/12/10 13:26:23 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 13:15:50 UT on 10 Dec 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 231210A (trigger 723906955.510584 / 231210553). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 137.9, Dec = 10.3 (J2000 degrees, equivalent to J2000 09h 11m, 10d 18'), with a statistical uncertainty of 14.4 degrees. The angle from the Fermi LAT boresight is 44.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2023/bn231210553/q...
