Shingles (GSI/QUB) OxQUB SN II 0.006 1 1 OxQUB The spectrum resembles a continuum dominated by galaxy light. However, there is a broad and shallow H-alpha component on top of the H-alpha emission from the host. We therefore designate a young SN II classification. Redshift from the known host (on NED). SNID template matches with SN II are provided in the related files tab. 2023TNSCR.871....1F
