[en] We report the discovery of strong flaring of the B3 II-III star HR2517. The evidence is based on Stroemgren differential uvby photometry spanning more than a decade. We discuss the behaviour of HR2517 in terms of two models, viz. a rooted bright spot suddenly appearing and developing with modulation in photospheric temperature producing periodic light and profile variations as the star rotates, or that HR2517 is a Be star in an eccentric (P~33-34d) high-mass X-ray binary (HMXB) with neutron star companion--one of the brightest such systems known.
