    We investigate the central environment of a Seyfert 1.5 galaxy IRAS 05078+1626 with the EPIC and RGS instruments onboard XMM-Newton. Our study represents the first X-ray spectroscopic measurement of this galaxy. The spectrum unveils some of the standard ingredients in Seyfert galaxies, such as a power law primary continuum, modified by reflection from the accretion disc and by the effect of complex, multi-phase obscuration. However, data constrains the accretion disc, if present, not to extend closer than to 60 gravitational radii from the black hole.
