Scientific paper

The paper reports photographic and spectroscopic observations of supernova 1973r, which occurred in a spiral arm of the SBb galaxy NGC 3627 (M66). It is shown that the supernova is a type II event and that the spectra are characterized by a strong continuum with superposed wide emission bands flanked on their violet edges by broad P Cyg absorptions. The absorption and emission features are found to drift progressively toward the red, and the expansion velocity of the ejected shells is found to decrease with time. B and V light curves are plotted, variations in the B-V color index are discussed, and the maximum magnitude of the supernova is estimated to be -16.4.
