Abstract

Light curves for the eclipsing binary XX Leo have been produced in the Johnson V and Cousins R bands. The light curves indicate that XX Leo is a contact or near-contact binary system with the relatively long period of 0.971130 day. The period of XX Leo has remained constant or nearly so since at least JD 2446110.
