UGC 11763 (Mkn 1513) is a Seyfert 1 galaxy. It has been observed with the XMM-Newton satellite in 2003, and this observation has lasted 39 Ks. On each observation, all the instruments on board the XMM-Newton satellite observe simultaneously the same object. In order to study the nature of the X-ray emission of this object, we have analysed the data obtained during the this observation. The energy observing range of three of the instruments (the EPIC cameras) goes from soft to hard X-rays and we use them to obtain the continuum characteristics of the source. The hard part of the spectra is well fitted with a power law, but the extrapolation of it to the soft part of the spectra shows that the source present an excess of flux below ~1keV . In the hard side of the X-ray spectra, the principal feature observed is a weak Fe-Kalpha fluorescence line. The RGS instruments observe only in the soft X-ray band but with a higher resolution than the others. Analysing these spectra we have found absorption and emission features that are signatures of the surrounding material of the active nucleus.
