TITLE: GCN CIRCULAR NUMBER: 39126 SUBJECT: GRB 250202C: Fermi GBM Final Real-time Localization DATE: 25/02/02 20:18:40 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 20:10:35 UT on 2 Feb 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250202C (trigger 760219840.823694 / 250202841). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 300.9, Dec = -54.5 (J2000 degrees, equivalent to J2000 20h 03m, -54d 30'), with a statistical uncertainty of 4.0 degrees. The angle from the Fermi LAT boresight is 25.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250202841/q...
