102016-01-14 02:03:56jujiaYuxin Xin, Jujia ZhangNoneSN IIP0.0149We obtained an optical spectrum (range 350-900 nm) of AT 2016I (ASASSN-16ai, ATel#8537) on UT 2016 Jan. 13.93 with the Li-Jiang 2.4 m telescope (LJT + YFOSC) at Li-Jiang observatory of Yunnan Observatories. The spectrum 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 Tonry 2007, Ap.J. 666, 1024) shows that it matches with SN 2004et at t = +6 days since the explosion. Given a recession velocity of 4467 km/s for the host galaxy UGC 09450, an expansion velocity of about 8500 km/s can be deduced from the H-alpha absorption minimum.
