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 (42 days). We will concentrate on new developments, particularly in the understanding of the anomalous equatorial emission and brightening regions in the jet. The anomalous emission is diffuse emission near the core region of SS433. This emission seems to be an outflow that brightens as it moves away from the jets at a velocity of ˜ 10000 km/s. The jets also contain brightening regions, where components brighten far out in the jets. This brightening does not always occur in the same place and sometimes dominates the light curve.
