The first multiply-imaged supernova, found in 2014 as an Einstein cross of four images around a cluster member galaxy (Kelly et al. 2015). Lens models predicted a further image about a year later (Treu et al. 2016), which appeared in December 2015 (Kelly et al. 2016a). Its time delays gave the first H0 measurement from a lensed supernova (Kelly et al. 2023b; Grillo et al. 2024). The references are papers centred on the supernova, its host or the lens models it tested.
