TITLE: GCN CIRCULAR NUMBER: 41099 SUBJECT: GRB 250716A: Fermi GBM Final Real-time Localization DATE: 25/07/16 01:39:42 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 01:29:06 UT on 16 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250716A (trigger 774322151.245036 / 250716062).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 65.7, Dec = -48.6 (J2000 degrees, equivalent to J2000 04h 22m, -48d 36'), with a statistical uncertainty of 1.0 degrees.
The angle from the Fermi LAT boresight is 126.0 degrees.
