Luminosity of SN 2020faa after accounting for MW extinction and distance, and integrating a BB fit to the gri photometry. A similar method was used for iPTF14hls which only had colour data past 150 days, and we can see that the early time emission of SN 2020faa nicely merges with the late time luminosity for iPTF14hls. Shown is the luminosity estimate for iPTF14hls from S19 up to 300 days (in green), assuming a constant bolometric correction at early times.
