  We present VLBI imaging results for SS433 from the period 1995-2000. An
equatorial emission region is detected and confirmed in 7 experiments at 1.6
and 5 GHz. The structure of the region changes with time on scales of weeks to
months. The nature of emission is unknown, but it is certainly non-thermal,
maybe optically thin synchrotron. The spectrum however might be attenuated by a
thermal population of electrons. There were previous indications for an
equatorial outflow from the system. We do detect outward motion of a radio
component, and estimate a speed of 1200/sin(i) km/s. Theoretical work and IR
observations suggest that the mass-loss rate in SS433 is much higher in this
region than in the jets. We suggest that the high-mass microquasars might all
have equatorial outflows; in fact, it is the dominant form of mass-loss in
these systems.
