Abstract
Synopic observations of MR Velorum (RX J0925.7-4758) taken over 5 months wi th the YALO telescope at CTIO have allowed us to narrow the window of accep table orbital periods. When these data are then combined with photometry ta ken over the past decade, a well-determined period of 4.0287822 +/-0.000002 6 days is found. It is now possible to phase together various published pho tometric and spectroscopic data.
