We obtained an optical spectrum (range 340-890 nm) of SN 2017cxz,discovered by Massimo Caimmi (ISSP), on UT April 12.83 2017 with the 2.4 m telescope (LJT + YFOSC) at LiJiang Gaomeigu Observatory of Yunnan Observatories (YNAO). The spectrum is consistent with that of a type Ib supernova in its early phase. Cross-correlation with a library of supernova spectra using the spectral comparison tool Gelato (Harutyunyan et al.,2008, A&A,488, 383) shows that the spectrum matches with SN 2008D at t= -11 days from the maximum light. Follow up observations are encouraged.
