TITLE: GCN CIRCULAR NUMBER: 43726 SUBJECT: GRB 260213B: Fermi GBM Final Localization DATE: 26/02/13 18:38:56 GMT FROM: oindabimukherjee@gmail.com The Fermi GBM team reports the detection of a likely LONG GRB "At 17:40:09.97 UT on 13 February 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260213B (trigger 792697214/260213736). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 145.98, Dec = -40.63 (J2000 degrees, equivalent to J2000 9h 43m, -40d 37'), with a statistical uncertainty of 3.63 degrees. The angle from the Fermi LAT boresight is 95 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2026/bn260213736/q...
