TITLE: GCN CIRCULAR NUMBER: 42907 SUBJECT: GRB 251130B: Fermi GBM Final Localization Correction DATE: 25/11/30 18:45:22 GMT FROM: rhamburg@usra.edu The Fermi GBM team reports the detection of a likely LONG GRB "At 15:33:18.11 UT on 30 November 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 251130B (trigger 786209603/251130648). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 78.82, Dec = -43.31 (J2000 degrees, equivalent to J2000 5h 15m, –43d 18'), with a statistical uncertainty of 1.74 degrees. The angle from the Fermi LAT boresight is 94 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251130648/q...
