Gamma-ray burst GRB 261114A, detected by the SVOM satellite on Nov. 14, 2026, showed an optical afterglow that stopped fading about 5,000 seconds after the trigger, according to NASA-hosted circulars. No redshift or X-ray afterglow has been reported, so the cause of the plateau stays open among magnetar energy injection, structured jets and layered ejecta.
