We present far-ultraviolet (FUV) spectral imaging observations of the Vela supernova remnant (SNR) obtained with the SPEAR/FIMS instrument. The Vela SNR extends ~8° in the FUV, and its global spectra are dominated by shock-induced emission lines. We find that the global FUV line luminosities can exceed the 0.1-2.5 keV soft X-ray luminosity by an order of magnitude. The global O VI : C III ratio shows that the Vela SNR has a relatively large fraction of slower shocks compared with the Cygnus…
