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 supercede the preliminary photometry published by Leibundgut et al (1991) and Phillips et al (1992). 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 general population of Type Ia supernova and accurate photometric indices needed for the Cepheid-supernova distance scale.

  1. The type Ia supernova 2023vjh: a peculiar 1991bg-like SN with unusually faint light curves

    astro-ph.HE 2026-07 accept novelty 5.0

    SN 2023vjh is an unusually faint 91bg-like SN Ia whose light curves and colors suggest possible CSM extinction despite minimal host interstellar dust signatures.
