TITLE: GCN CIRCULAR NUMBER: 43716 SUBJECT: GRB 260212A: Fermi GBM Final Real-time Localization DATE: 26/02/12 17:59:41 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 17:49:08 UT on 12 Feb 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260212A (trigger 792611353.21224 / 260212742). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 228.9, Dec = 74.1 (J2000 degrees, equivalent to J2000 15h 15m, 74d 05'), with a statistical uncertainty of 1.1 degrees. The angle from the Fermi LAT boresight is 127.0 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260212742/q...
