Top panel: multiband light curves of SN 2017ens. Note the discontinuous abscissa. Middle panel: light-curve comparison in absolute g-band with the SNe chosen for spectroscopic comparison. Bottom panel: bolometric light curve of SN 2017ens and model fitting. The pseudobolometric luminosity and photometry of SN 2017ens (UV through NIR) is available as data behind the figure. The data used to create this figure are available.
