TITLE: GCN CIRCULAR NUMBER: 40883 SUBJECT: GRB 250702B: Fermi GBM Final Real-time Localization DATE: 25/07/02 14:06:41 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 13:56:05 UT on 2 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250702B (trigger 773157370.765606 / 250702581). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 286.0, Dec = -8.7 (J2000 degrees, equivalent to J2000 19h 03m, -8d 41'), with a statistical uncertainty of 7.8 degrees. The angle from the Fermi LAT boresight is 90.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250702581/q...
