Some comparisons of theoretical supernova light curves with supernova 19691 (Type II) in NGC 1058

Using the empirical transformations of Kirshner and Kwan, we compare the UBV photometry of Ciatti, Rosino, and Bertola for Type II supernova SN 19691 in NGC 1058 with the theoretical predictions of Falk and Arnett. Spectra and spectral scans by these observers are used to infer fluid velocities. The behavior as a function of time of (1) the effective temperature, (2) the fluid velocity, and (3) the photospheric radius is compared in detail. The only adjustment made is to synchronize the observational and theoretical times at maximum effective temperature. The agreement is good
