TITLE: GCN CIRCULAR NUMBER: 42901 SUBJECT: GRB 251130A: Fermi GBM Final Real-time Localization DATE: 25/11/30 00:53:39 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 00:43:07 UT on 30 Nov 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 251130A (trigger 786156192.430142 / 251130030). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 176.6, Dec = -60.4 (J2000 degrees, equivalent to J2000 11h 46m, -60d 23'), with a statistical uncertainty of 5.1 degrees. The angle from the Fermi LAT boresight is 99.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn251130030/q...
