TITLE: GCN CIRCULAR NUMBER: 41140 SUBJECT: GRB 250723A: Fermi GBM Final Real-time Localization DATE: 25/07/23 13:23:34 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 13:13:04 UT on 23 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250723A (trigger 774969189.599836 / 250723551). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 65.3, Dec = 38.4 (J2000 degrees, equivalent to J2000 04h 21m, 38d 23'), with a statistical uncertainty of 6.2 degrees. The angle from the Fermi LAT boresight is 54.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250723551/q...
