Abstract
We present a phase-resolved ROSAT HRI X-ray light curve of the dwarf nova O Y Car in quiescence. The X-ray flux is eclipsed at the same time as the opt ical eclipse of the primary, and the region of X-ray emission is comparable in size to the white dwarf, We use subsequent optical observations to upda te the orbital ephemeris of the system.
