TITLE: GCN CIRCULAR NUMBER: 41117 SUBJECT: GRB 250718A: Fermi GBM Final Real-time Localization DATE: 25/07/18 07:16:14 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 SHORT GRB At 07:05:40 UT on 18 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250718A (trigger 774515145.094648 / 250718296). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 233.0, Dec = -26.0 (J2000 degrees, equivalent to J2000 15h 31m, -26d 00'), with a statistical uncertainty of 20.3 degrees. The angle from the Fermi LAT boresight is 119.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250718296/q...
