TITLE: GCN CIRCULAR NUMBER: 30962 SUBJECT: GRB 211024A: Fermi GBM Final Real-time Localization DATE: 21/10/24 01:44:24 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 01:34:11 UT on 24 Oct 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 211024A (trigger 656732056.398738 / 211024065). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 358.1, Dec = 3.1 (J2000 degrees, equivalent to J2000 23h 52m, 3d 06'), with a statistical uncertainty of 16.9 degrees. The angle from the Fermi LAT boresight is 88.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2021/bn211024065/q...
