Half a year after its outburst, the nova V4743 Sgr evolved into the brightest super-soft X-ray source in the sky with a flux maximum around 30A, exhibiting resonance lines of C V, C VI, N VI, N VII, and O VII. We present preliminary results of an analysis of the XMM-Newton RGS spectra by means of NLTE model-atmosphere techniques.
