TITLE: GCN CIRCULAR NUMBER: 36037 SUBJECT: GRB 240405A: Fermi GBM Final Real-time Localization DATE: 24/04/05 15:17:52 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 15:06:46 UT on 5 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240405A (trigger 734022411.49845 / 240405630). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 289.6, Dec = 37.8 (J2000 degrees, equivalent to J2000 19h 18m, 37d 47'), with a statistical uncertainty of 5.2 degrees. The angle from the Fermi LAT boresight is 143.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240405630/q...
