ROSAT observations of the W 50/SS 433 system. SS 433 and the surrounding supernova remnant W 50 were observed inseveral pointings between March 1991 and March 1993 with the PSPConboard ROSAT for a total of more than 60ksec. The soft X-ray flux fromSS 433 varies by up to a factor of two but no clear correlation could befound with precessional or binary phase. The temperature of the best fitthermal spectrum cannot be constrained accurately, but kT>2keV. TheN_H_ value towards SS 433 itself seems to be higher than to the rest ofthe remnant. The two oppositely directed X-ray jets show differentmorphological and spectral properties indicating a strong influence ofthe surrounding matter onto the energy loss mechanism of the jet. Thespectrum of the eastern jet is non-thermal with a power law photon index{GAMMA}~1.6. The jet terminates in a region with thermal emission withstrong spatial similarities between the X-ray and the radio structures.The western jet has a considerably softer X-ray spectrum, either ofthermal origin or with a steep power law ( {GAMMA}>2.3).
