TITLE: GCN CIRCULAR NUMBER: 41150 SUBJECT: GRB 250725A: Fermi GBM Final Real-time Localization DATE: 25/07/25 02:01:58 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 01:51:34 UT on 25 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250725A (trigger 775101099.80868 / 250725077). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 31.5, Dec = -85.4 (J2000 degrees, equivalent to J2000 02h 06m, -85d 24'), with a statistical uncertainty of 1.0 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/2025/bn250725077/q...
