TITLE: GCN CIRCULAR NUMBER: 42272 SUBJECT: GRB 251014C: Fermi GBM Final Localization DATE: 25/10/14 21:48:07 GMT FROM: Suman Bala at USRA <sumanbala2210@gmail.com> The Fermi GBM team reports the detection of a likely LONG GRB "At 20:45:58.96 UT on 14 October 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 251014C (trigger 782167563/251014865). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 133.36, Dec = 14.24 (J2000 degrees, equivalent to J2000 8h 53m, +14d 14'), with a statistical uncertainty of 5.09 degrees. The angle from the Fermi LAT boresight is 84 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251014865/q...
