Abstract

The unusual X-ray binary system SS 433 emits two oppositely directed jets which precess over a period of 162.5 days (Margon 1984). The Doppler shifts of the moving optical lines correspond to a velocity of material in the jets of 0.26c. Radio maps show that the jets give rise to radio emission which extends over scales from ≲ 10 mas (e.g. Schilizzi et al. 1984) through ~ 1 arc sec (Hjellming and Johnston 1981a) to several arc minutes (Downes et al. 1981). We present radio maps made recently with VLBI and MERLIN.
