TITLE: GCN CIRCULAR NUMBER: 38977 SUBJECT: GRB 250119A: Fermi GBM Final Real-time Localization DATE: 25/01/19 02:10:06 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 01:59:27 UT on 19 Jan 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250119A (trigger 758944772.334442 / 250119083). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 204.1, Dec = 43.1 (J2000 degrees, equivalent to J2000 13h 36m, 43d 06'), with a statistical uncertainty of 23.4 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/bn250119083/q...
