A spectroscopic orbit has been determined for the faint double lined eccentric eclipsing binary AN Cam. The radial velocities were obtained with the Coravel radial velocity spectrometer. Using 40 Coravel measurements for the primary component and 34 for the secondary, the spectroscopic orbit was calculated, yielding very accurate elements. Considerations about spectral type, duration of main eclipse and consecutive loss of light and other parameters deduced from Coravel peaks, lead to the adoption of this system, a model in very close agreement with the whole spectroscopic and photometric data.
