We report an optical spectrum (range 370-870 nm) of ASASSN-16ad (ATEL 8521) that was obtained on UT Jan.10.6 2016 with the 2.16-m telescope (+BFOSC) at the Xinglong Station of National Astronomical Observatories of China. The spectrum is consistent with that of a type Ia supernova at a few days before the maximum light. After correcting for a redshift of 0.016 for its host galaxy PGC 006137, an expansion velocity of about 14600 km/s can be derived from the absorption minimum of Si II 635.5 nm line.
