TITLE: GCN CIRCULAR NUMBER: 36012 SUBJECT: GRB 240402A: Fermi GBM Final Real-time Localization DATE: 24/04/02 23:54:34 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 23:44:04 UT on 2 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240402A (trigger 733794249.222788 / 240402989). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 220.9, Dec = 29.3 (J2000 degrees, equivalent to J2000 14h 43m, 29d 18'), with a statistical uncertainty of 25.0 degrees. The angle from the Fermi LAT boresight is 98.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240402989/q...
