Abstract: Southern hemisphere cataclysmic variable OY Carinae is an eclipsing SU UMa—type dwarf nova. With the orbital period about 91 min it belongs to the dwarf novae below the period gap. Three new eclipses were measured at the La Silla observatory in Chile using the Danish 1.54-m telescope from November 2012 to March 2013. We constructed an observed-minus-calculated diagram using new and published mid—eclipse times. At the O-C diagram there are clearly visible sinusoidal variations of the orbital period similar to many other cataclysmic variables.
