The Galactic X-ray binary SS433 is the best known example of a precessing relativistic jet. Here we present the results of a campaign to image SS433 daily with the Very Long Baseline Array over a quarter of its precession period (40 days). These observations provide the best high resolution data set to study the evolution and dynamics of the radio emission in SS433. This unprecedented look at SS433 will allow us to: characterize the newly discovered anomalous equatorial emission; clarify the distance to SS433 (over which there is some debate); and explore the the dynamic and flux density evolution of individual components over a substantial fraction of their lives.
