Photographic, spectroscopic, and photometric data obtained during 13 days of observation in April 1983 of the bright 1983 supernova in NGC 4753 are presented and discussed. The general appearance of the spectra is that of a typical type I event, including prominent features at wavelengths of about 3970 and 4600. The UBV photometry results are also typical of this class of supernovae. The light curve results suggest that the 1983 event may be one of Barbon's 'fast class' of supernovae.
