TITLE: GCN CIRCULAR NUMBER: 44116 SUBJECT: GRB 260325A: Fermi GBM Final Localization DATE: 26/03/26 02:06:55 GMT FROM: Suman Bala at USRA <sumanbala2210@gmail.com> The Fermi GBM team reports the detection of a likely LONG GRB "At 23:39:37.55 UT on 25 March 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260325A (trigger 796174782/260325986). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 113.3, Dec = -59.7 (J2000 degrees, equivalent to J2000 7h 33m, -59d 43'), with a statistical uncertainty of 3.2 degrees. The angle from the Fermi LAT boresight is 134 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260325986/q...
