TITLE: GCN CIRCULAR NUMBER: 36699 SUBJECT: GRB 240619B: Fermi GBM Final Real-time Localization DATE: 24/06/19 11:21:29 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 11:10:47 UT on 19 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240619B (trigger 740488252.364386 / 240619466). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 116.0, Dec = 18.4 (J2000 degrees, equivalent to J2000 07h 44m, 18d 23'), with a statistical uncertainty of 20.9 degrees. The angle from the Fermi LAT boresight is 68.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240619466/q...
