Radio (Dickel et al. 1993), X-ray (Warren et al. 2003) and IR 24-micron (Williams et al. 2006) observations of N63A show a complete shell. However, the bright optical emission (Chu et al 1999), and the emission in near- to mid-infrared bands (Williams et al. 2006), is confined to a three-lobed structure on the western side of the SNR. Levinson et al. (1995) showed that the two eastern lobes of this nebula have high [SII]/H-alpha ratios, indicative of shock ionization, while the optical spectrum of the western lobe is more consistent with the photoionization in HII regions.
