TITLE: GCN CIRCULAR NUMBER: 45071 SUBJECT: GRB 260703B: Fermi GBM Final Localization DATE: 26/07/03 19:21:18 GMT FROM: Angus Jameson <abj0023@uah.edu> The Fermi GBM team reports the detection of a likely LONG GRB "At 02:25:05.66 UT on 03 July 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260703B (trigger 804738310/260703101). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 310.5, Dec = 47.9 (J2000 degrees, equivalent to J2000 20h 42m, +47d 54'), with a statistical uncertainty of 5.1 degrees. The angle from the Fermi LAT boresight is 19 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260703101/q...
