Scientific paper

Spectra and type identifications for three supernovae are given. Supernovae 1970j, 1971l, and 1971u are found to be of type I. Synthetic fits to the spectrum of SN 1971l suggest that Fe II emission lines play a dominant role in determining the character of the spectrum for the wavelength interval between 3600 and 6800 A. Evidence for He II is strongly suggested. Other lines contributing to the emission spectrum are the Na I D lines, the H and K lines of Ca II, and the alpha through delta lines of the Balmer series of hydrogen.
