TITLE: GCN CIRCULAR NUMBER: 39320 SUBJECT: GRB 250214A: Fermi GBM Final Real-time Localization DATE: 25/02/14 05:42:39 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 05:32:07 UT on 14 Feb 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250214A (trigger 761203932.174936 / 250214231).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 122.8, Dec = -41.9 (J2000 degrees, equivalent to J2000 08h 11m, -41d 53'), with a statistical uncertainty of 5.3 degrees.
The angle from the Fermi LAT boresight is 122.0 degrees.
