TITLE: GCN CIRCULAR NUMBER: 37362 SUBJECT: GRB 240831A: Fermi GBM Final Real-time Localization DATE: 24/08/31 15:05:55 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 14:54:49 UT on 31 Aug 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240831A (trigger 746808894.48422 / 240831621). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 286.3, Dec = 40.2 (J2000 degrees, equivalent to J2000 19h 05m, 40d 12'), with a statistical uncertainty of 1.1 degrees. The angle from the Fermi LAT boresight is 167.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240831621/q...
