We obtained an optical spectrum (range 385-880 nm) of the transient AT 2020zoq(=ASASSN-20oc), discovered by the ASASSN (All-Sky Automated Survey for Supernovae), on UT 2020 Nov.14 21:21:06.00 with the Xinglong 2.16-m telescope (+BFOSC) of NAOC. The spectrum is characterized by blue featureless continuum, with prominent absorption at around 4400 Angstrom. Based on the spectral classification tool GELATO (Harutyunyan et al. 2008, A&A, 488, 383), the spectrum of SN 2020zoq is found to match that of type IIP SN 1999gi at t=+3.8 day after explosion. From the narrow emission line of Ha in the spectrum, a redshift of z=0.01004 can be deduced for the host galaxy UGC 05760.
