Moore (Queen's University Belfast) OxQUB SN II 0.02 1 OxQUB The spectrum resembles that of a blue continuum with faint broad features. Several matches with SNe II two weeks before maximum light were obtained using SNID (e.g., SN2011fu at t = -14d). Redshift from SNID template matching. 2022TNSCR1138....1F
