We have re-analysed all available high-resolution ultraviolet IUE spectra of the high-mass X-ray binary HD 153919/4U 1700-37. The radial velocity semi-amplitude of km s-1 and orbital eccentricity of agree very well with the values obtained earlier from optical spectra. They disagree with earlier conclusions for the same data reduced by Heap & Corcoran ([CITE]) and by Stickland & Lloyd ([CITE]).
