Forecast of the reappearance dates for SN Encore image 1d (top panel) and SN Requiem image 2d (bottom panel). The prediction from the weighted combination of the seven models is shown in black, with shaded 1σ uncertainties, assuming a 1% time-delay uncertainty. The H₀ measurements from Planck Collaboration VI (2020) and SH0ES (Riess et al. 2022) with their 1σ uncertainties are overlaid. Given the long time delays of images 1d and 2d, detecting the reappearance of each SN enables time-delay measurements with ∼1% uncertainty and H₀ with 2−3% uncertainty.
