TITLE: GCN CIRCULAR NUMBER: 37627 SUBJECT: GRB 240929A: Fermi GBM Final Real-time Localization DATE: 24/09/29 20:00:32 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 19:50:04 UT on 29 Sep 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240929A (trigger 749332209.094252 / 240929826). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 356.1, Dec = 75.0 (J2000 degrees, equivalent to J2000 23h 44m, 75d 00'), with a statistical uncertainty of 1.4 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/2024/bn240929826/q...
