We obtained an optical spectrum (range 350-900 nm) of AT 2016aqp on UT 2016 Feb. 27.5 with the Li-Jiang 2.4 m telescope (LJT + YFOSC) at Li-Jiang observatory of Yunnan Observatories. The pectrum is similar to that of a Type-IIP supernova at a few days after explosion. Cross-correlation with a library of supernova spectra using the "Supernova Identification" code (SNID; Blondin and onry 2007, Ap.J. 666, 1024) shows that it matches with SN 2005cs at t = +4 days. Given a recession velocity of 4720 km/s for the host galaxy PGC 16065, an expansion velocity of about 8700 km/s can be deduced from the H-alpha absorption minimum.
