We here report an identification of SDSSJ141324+530527.0 (SBS1411+533) at$z=0.456344$ as a new "changing-look" quasar with a "turn-on" spectral typetransition from Type-1.9/2 to Type-1 within a rest frame time scale of 1-10 yrby a comparison of our new spectroscopic observation and the Sloan Digital SkySurvey (SDSS) archive data base. The SDSS DR7 spectrum taken in 2003 isdominated by a starlight emission from host galaxies redward of the Balmerlimit, and has non-detectable broad H$\beta$ line. The new spectrum taken by uson June 1st, 2017 and SDSS DR14 spectrum taken on May 29, 2017 indicate thatthe object is of a typical quasar spectrum with a blue continuum and strongBalmer broad emission lines. In addition, an intermediate spectral type can beidentified in the SDSS DR13 spectrum taken in 2015. The invariability of theline wing of MgII$\lambda2800$ emission and time scale argument (Theinvariability of [OIII]$\lambda$5007 line blue asymmetry) suggests that avariation of obscuration (an accelerating outflow) is not a favorable scenario.The time scale argument allows us to believe the type transition is possiblycaused by either a viscous radial inflow or a disk instability around a$\sim5-9\times10^{7}M_\odot$ black hole.
