We present new high-fidelity images of the X-ray binary with twin relativistic radio jets, SS433. These images are from simultaneous observations with the VLBA, MERLIN and the VLA, which are sensitive to structures on many size-scales and give images with a physical resolution approaching several AU. We observed in this mode for three successive nights and will present updated refinements to the jet parameters inferred from the rapid evolution of this source over these timescales. We will discuss the `anomalous ejection' emanating from the core perpendicular to the jets which this unique dataset reveals.
