Dong (KIAA-PKU) ASAS-SN AGN 0.0504 1 ASAS-SN We obtained an optical low-resolution spectrum of supernovae candidates on UT 2018 July 15 with WFCCD mounted on the du Pont 2.5m telescope at Las Campanas Observatory. The spectrum of ASASSN-18mm/AT2018cmp is that of a Type II AGN. SNID (Blondin & Tonry 2007) gives a best fit z=0.051 as the redshift, consistent with the host galaxy redshift. 2018TNSCR.988....1K
