TITLE: GCN CIRCULAR NUMBER: 39294 SUBJECT: GRB 250212A: Fermi GBM Final Real-time Localization DATE: 25/02/12 01:00:30 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 00:49:53 UT on 12 Feb 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250212A (trigger 761014198.925334 / 250212035). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 282.5, Dec = 52.8 (J2000 degrees, equivalent to J2000 18h 49m, 52d 47'), with a statistical uncertainty of 8.1 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/2025/bn250212035/q...
