Abstract
Observations of two eclipses of the dwarf nova OY Carinae are presented. The results obtained confirm that neither of the linear ephemerides presented in the astronomical literature appear to model accurately the observed results. Quadratic and sinusoidal alternatives are assessed and both appear to offer closer, but not perfect, predictive tools.
