We here report an identification of SDSS J141324+530527.0 ( SBS 1411+533 ) at z = 0.456344 as a new “ changing-look ” quasar with a “ turn-on ” spectral type transition from Type-1.9/2 to Type-1 within a rest frame time scale of 1-10 yr by a comparison of our new spectroscopic observation and the Sloan Digital Sky Survey ( SDSS ) archive data base . The SDSS DR7 spectrum taken in 2003 is dominated by a starlight emission from host galaxies redward of the Balmer limit , and has non-detectable broad H \beta line . The new spectrum taken by us on June 1st , 2017 and SDSS DR14 spectrum taken on May 29 , 2017 indicate that the object is of a typical quasar spectrum with a blue continuum and strong Balmer broad emission lines . In addition , an intermediate spectral type can be identified in the SDSS DR13 spectrum taken in 2015 . The invariability of the line wing of \ion Mg2 \lambda 2800 emission and time scale argument ( The invariability of [ \ion O3 ] \lambda 5007 line blue asymmetry ) suggests that a variation of obscuration ( an accelerating outflow ) is not a favorable scenario . The time scale argument allows us to believe the type transition is possibly caused by either a viscous radial inflow or a disk instability around a \sim 5 - 9 \times 10 ^ { 7 } M _ { \odot } black hole .
