PG 1244+026 is a an extremely bright active galaxy (AGN) with the narrowest H-beta line among all PG quasars. Its broadband spectral energy distribution (SED) shows a huge soft X-ray excess making this object a perfect test for our models of NLS1 which are dominated by large hot discs. Here we propose to observe this object in order to study its X-ray spectrum and spectral variability. A long exposure time XMM-Newton observation will resolve detailed features in its X-ray spectrum and RMS spectrum, especially in the soft-excess region. This study will help us to understand the nature of the most extreme NLS1s, and provide essential evidence towards the unification of the accretion processes between AGN and black hole binaries (BHBs).
