TITLE: GCN CIRCULAR NUMBER: 40886 SUBJECT: GRB 250702D: Fermi GBM Final Localization Correction DATE: 25/07/02 15:19:41 GMT FROM: eliza.neights@gmail.com The Fermi GBM team reports the detection of a likely LONG GRB "At 13:09:02.03 UT on 02 July 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250702D (trigger 773154547/250702548). This trigger was initially classified as Below horizon by the flight software, but is in fact a GRB. The on-ground calculated location, using the Fermi GBM trigger data, is RA = 292.86, Dec = 3.55 (J2000 degrees, equivalent to J2000 19h 31m, +3d 32'), with a statistical uncertainty of 14.69 degrees. The angle from the Fermi LAT boresight is 92 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2025/bn250702548/q...
