We report the discovery of a Narrow Line QSO located at about 1.3' from the Broad Line Radio Galaxy 3C 445. The source, 1WGA J2223.7-0206, although already revealed by ROSAT, has never been optically identified previously. An XMM-Newton observation of 3C 445 has allowed, for the first time, an accurate X-ray spectral study of 1WGA J2223.7-0206, revealing an ultra-soft spectrum and fast flux variations typical of Narrow Line AGN. The 0.2-10 keV spectrum is well represented by a power law ( ) plus a black body component ( kT = 117 eV) absorbed by Galactic . About of the X-ray flux ( 10-13 erg cm -2 s -1) is emitted below 2 keV. The 0.2-2 keV flux is observed to decrease by about a factor 1.6 in about 5000 s.
