TITLE: GCN CIRCULAR NUMBER: 42237 SUBJECT: GRB 251014A: Fermi GBM Final Real-time Localization DATE: 25/10/14 00:39:10 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 SHORT GRB
At 00:28:30 UT on 14 Oct 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 251014A (trigger 782094515.336852 / 251014020).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 114.7, Dec = 7.4 (J2000 degrees, equivalent to J2000 07h 38m, 7d 24'), with a statistical uncertainty of 8.3 degrees.
The angle from the Fermi LAT boresight is 45.0 degrees.
