TITLE: GCN CIRCULAR NUMBER: 43096 SUBJECT: GRB 251214C: Fermi GBM Final Localization DATE: 25/12/14 13:08:43 GMT FROM: Marianna Dafčíková at Masaryk University 500025@mail.muni.cz
The Fermi GBM team reports the detection of a likely LONG GRB
"At 09:17:32.51 UT on 14 December 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 251214C (trigger 787396657/251214387).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 346.3, Dec = 41.0 (J2000 degrees, equivalent to J2000 23h 05m, +41d 0'), with a statistical uncertainty of 6.0 degrees.
The angle from the Fermi LAT boresight is 138 degrees.
