Images of the inner portion of M83, including the region surrounding the site of SN 1957D, were obtained using narrow-band interference filters for lines of H-alpha, forbidden S II, forbidden O I, and forbidden O III, as well as a continuum band centered at 6100 A. The forbidden III 4959-A, 5007-A lines have a FWHM of about 2500 km/s, confirming that the emission nebula is due to the SN. The results show the object to be the youngest ejecta-dominated SNR observed to date. 20 refs.
