At the position of the recently recovered radio source, there is now a nebula bright in [O III], but also visible in [S II], [O I], and Hα. Spectroscopy of the nebulosity shows that the [O III] λλ4959, 5007 lines are broad-- ~ 2500 km s^-1^ (FWHM) -- confirming that the emission nebula is due to the supernova and indicating that the explosion was that of a massive star. This object is the newest and certainly the youngest addition to the class of ejecta-dominated supernova remnants such as Cas A. There is no evidence of emission from any of the four other historical supernovae in M83.
