3. Conclusions

The combination of photometric and magnetic observations of the star HD 208217 allowed the derivation of its rotational period as . The optical lightcurves and the magnetic modulus variations appear to be highly anharmonic and the photometric amplitudes are strongly wavelength dependent. It is interesting to note that HD 208217 is the only star known to present a double-wave structure in the magnetic field modulus variations (Mathys et al. 1996). All this suggests a rather uncommon atmospheric structure and shows the need for additional magnetic observations.
