Subtracted continuum (assumed black-body fitting) spectra of LSQ14mo at explosion epochs + 8.8 d, + 15.2 d, and + 21.7 d. The identification of spectral element features are the same at those three epochs. This supports the idea that the blue continuum observed in the + 8.8 d spectrum could be due to an additional energy source that likely comes from the interaction between the SN ejecta and a thin CO shell.
