B. WILLIAMS Department of Physics and Astronomy, Rutgers University, P.O. Box 849, Piscataway, NJ 08855 Received 1997 July 14; revised 1997 September 24 ABSTRACT We present UBVRI light curves for the bright Type Ia supernovae SN 1990N in NGC 4639 and SN 1991T in NGC 4527, based on photometry gathered in the course of the Calan/Tololo supernova program. Both objects have well-sampled light curves starting several days before maximum light and spanning well through the exponential tail. These data supersede the preliminary photometry published by Leibundgut et al. and Phillips et al. The host galaxies for these supernovae have (or will have) accurate distances based on the Cepheid period-luminosity relationship. The photometric data in this paper provide template curves for the study of the general population of Type Ia supernovae and accurate photometric indices, needed for the Cepheid-supernova distance scale. Key words: galaxies: distances and redshifts - supernovae: individual (1990N, 1991T) ======================================================================= 1998AJ....116.1006L ERRATUM: "OPTICAL LIGHT CURVES OF THE TYPE Ia SUPERNOVAE SN 1990N AND SN 1991T" [ASTRON.

Box 849, Piscataway, NJ 08855 Received 1998 May 11 The following errors were brought to our attention by Brian Skiff of the Lowell Observatory. In Table 3, two local standard stars were omitted, leading to confusion between the stars listed and those shown in Figure 1 of the paper. We provide a corrected version of the table below.
