TITLE: GCN CIRCULAR NUMBER: 41064 SUBJECT: GRB 250711A: Fermi GBM Final Real-time Localization DATE: 25/07/11 14:50:44 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 14:40:12 UT on 11 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250711A (trigger 773937617.940244 / 250711611). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 261.2, Dec = 44.9 (J2000 degrees, equivalent to J2000 17h 24m, 44d 53'), with a statistical uncertainty of 1.2 degrees. The angle from the Fermi LAT boresight is 28.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250711611/q...
