IUE observations of the cataclysmic variable 1 H0551-819 obtained at three different epochs reveal P-Cygni type profiles in the CIV line. The shape of these profiles is modulated with the orbital period of the system. The observations suggest the presence of a wind in the system. We considered several models of wind, disc and continuum emitting hotspot that could account for the orbital modulation of the line profiles but none of them gave satisfactory results.
