Abstract
Previous photometry of the variable WN5 star EZ CMa shows that it has a constant period of 3.7658 ± 0.0007 days, but a light curve that has varied in shape and amplitude over the past 15 years. Subsidiary peaks or possible secondary periods have been observed in this time. These photometric variations may be explained by either binary modulation, pulsation or rotation-related phenomenon. The detection of a long term period of 10.24±0.03 days, is presented, with a montage of all light curves of EZ CMa plotted over the past 15 years.
