The use of Type Ia supernovae as cosmological tools has reinforced the need to better understand these objects and their light curves. The light curves of Type Ia supernovae are powered by the nuclear decay of 56Ni →56 Co →56 Fe. The late time light curves can provide insight into the behavior of the decay products and their eﬀect of the shape of the curves. We present the optical light curves of six “normal” Type Ia supernovae, obtained at late times with template image subtraction, and the ﬁts of these light curves to supernova energy deposition models.
