Left: spectral energy distributions of SNhunt120 constructed from our optical photometry and complemented with photometry from Bond (2018). The best-fit BB is overplotted on each SED function; red lines are the fit to CSP-II data, and black lines are the fit to Bond data. For clarity, the SEDs are shifted by arbitrary constants, and the phase of each SED relative to the epoch of discovery is indicated. Right: resulting time evolution of the BB luminosity (top), BB temperature (middle), and BB radius (bottom) of the underlying emission region corresponding to the BB fits.
