We present preliminary results of a 50 ks long XMM-Newton obs ervation of the bright Z-source GX 340+0. We study the temporal and spectral variability of t he source, performing a time resolved analysis. In the energy spectra, a broad asymmetri c emission line in the Fe K α energy band is always present. Its shape is compatible with a relati vistically smeared profile arising from reflection on a hot accretion disk extending close to the cent ral accreting neutron star. Despite a significant change in the continuum emission and luminosity , the line profile remains substantially unchanged. The line is produced by recombination of highly i onized iron (Fe XXV), the reflecting disk has an inner radius close to 10 gravitational radii, whi le the fit requires a high value for the outer disk radius. The inclination of the source is well cons trained at 35 deg, while the emissivity index is -2.33.
