General information
Fermi-GBM reports a likely long GRB, GRB 260514A, triggered at 2026-05-14 04:56:40 UT with a large statistical localization uncertainty. Optical follow-up includes MASTER upper limits and an SVOM/VT report of an uncatalogued optical source for EP260514a, though the provided circulars do not explicitly establish this as the GRB 260514A counterpart.
