DESCRIPTION:We present new analysis of the X-ray spectra of the Seyfert 1 
 galaxy NGC 3516 as seen by the XMM-Newton RGS and EPIC-pn in recent observ
 ations\, with the emphasis put on high resolution spectroscopy. NGC 3516 s
 hows interesting spectral and flux variability during four observations in
  2006\; we investigate whether this is due to absorption by the warm absor
 ber and/or is intrinsic to the source emission. We show that the passage o
 f an absorbing cloud\, part of a clumpy disk wind model\, is unable to acc
 ount for this variability. Intrinsic changes in the source continuum are f
 ound to play a much more significant role in explaining the observed flux 
 and spectral variability than originally thought for this AGN.
