Abstract
We present late-epoch optical photometry (BVRI) of seven normally luminous and superluminous Type la super-novae: SN 2000E, SN 2000ce, SN 2000cx, SN 2001C, SN 2001V, SN 2001bg, and SN 2001dp. The photometry of these objects was obtained using a template subtraction method to eliminate galaxy light contamination during aperture photometry. We show the optical light curves of these supernovae out to epochs of up to ∼640 days after the explosion of the supernova. We show a linear decline in these data during the epoch of 200-500 days after explosion, with the decline rate in the B, V, and R bands equal to about 1.4 mag per 100 days, but the decline rate of the I-band is much shallower at 0.94 mag per 100 days.
