By means of the CaT line at $8662$ \\AA, we measured its redshift $z=1.386\\pm 0.001$ and we estimated its velocity dispersion $\\sigma_{v}=340 ^{-60}_{+120}$ km/s. Its corresponding virial mass is 3.9$\\times10^{11}$ M$_\\odot$, compatible with the stellar mass estimates obtained assuming Initial Mass Functions (IMFs) less dwarf rich than the Salpeter one.
