  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 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 MgII$\lambda2800$ emission and time scale argument (The
invariability of [OIII]$\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
$\sim5-9\times10^{7}M_\odot$ black hole.
