Shingles (GSI/QUB) OxQUB SN Ia-91T-like 0.073 1 OxQUB Several matches with normal Ia and Ia-91T SNe at around maximum light were obtained using SNID (e.g., SN2005hj at t = -4d). Given the peak absolute magnitude of M_o = -19.8 in ATLAS, a Ia-91T classification seems more appropriate. Redshift from the known host (on NED). 2023TNSCR.670....1F
