Photometry of the Type Ia Supernovae 1999cc, 1999cl, and 2000cf

We present previously unpublished BVRI photometry of the Type Ia supernovae 1999cc and 2000cf along with revised photometry of SN 1999cl. We confirm that SN 1999cl is reddened by highly nonstandard dust, with RV = 1.55 ? 0.08. Excepting two quasar-lensing galaxies whose low values of RV are controversial, this is the only known object with a published value of RV less than 2.0. SNe 1999cl and 2000cf have near-infrared absolute magnitudes at maximum in good agreement with other Type Ia supernovae of midrange decline rates.
