Photometric and spectroscopic observations of DO Leo have been obtained using the McDonald Observatory high-speed CCD photometer and a conventional two-channel photoelectric photometer. The data reveal eclipses that are approximately 1.5 m deep. A total of nine eclipses were observed in February and March 1988 and in April 1989. These data were used to establish an orbital period of 0.2345147(2) d. A low-resolution optical spectrum reveals significant He II 4686 emission in addition to the characteristic Balmer and He I emission lines.
