TITLE: GCN CIRCULAR NUMBER: 36958 SUBJECT: GRB 240727A: Fermi GBM Final Real-time Localization DATE: 24/07/28 00:02:26 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 23:51:46 UT on 27 Jul 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240727A (trigger 743817111.069264 / 240727994). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 115.5, Dec = -33.0 (J2000 degrees, equivalent to J2000 07h 42m, -33d 00'), with a statistical uncertainty of 6.0 degrees. The angle from the Fermi LAT boresight is 22.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240727994/q...
