Abstract
We present preliminary results of the X-ray analysis of XMM-Newton and Swift observations as part of a multi-wavelength monitoring campaign in 2012 of the radio-loud narrow line Seyfert 1 galaxy PKS 2004-447. The source was recently detected in gamma-rays by Fermi/LAT among only four other galaxies of that type. The 0.5 - 10 keV X-ray spectrum is well-described by a simple absorbed powerlaw (Gamma similar to 1.6). The source brightness exhibits variability on timescales of months to years with indications for spectral variability, which follows a "bluer-when-brighter" behaviour, similar to blazars.
