A series of MERLIN observations at λ6 cm of the peculiar object SS433 were made during the spring/summer of 1982. The maps obtained by hybrid mapping show that an elongated structure was formed, extending to ~1 arcsec in length before evolving into two symmetrically placed knots of radio emission straddling a central unresolved core. The structures can be compared with the loci of radio emission expected on the twin jet model for SS433. The knots C and D clearly visible on the map of 820514 (= JD2445104, Figure 1) fit the locus well and were ejected on JD2445085 ±2 at the same time as a strong outburst in the X band total power (Johnston et al. 1983). Knots A and B were ejected earlier but do not lie on the expected locus, even if allowance for the nodding motions proposed by Katz et al. 1982 is made.
