ABSTRACT
The Hopkins Ultraviolet Telescope was used during the Astro--2 space shuttle
mission in 1995 March to observe emission lines of H I, He II, C IV, N V, and O VI from
the faint optical Balmer line filament at the northwest edge of the SN1006 supernova
remnant. This is the first successful far ultraviolet observation of a nonradiative shock
wave with velocity in excess of 300 km s \Gamma1 , and the first detection of ultraviolet emission
lines from SN1006. The observed line widths are consistent with the ¸2300 km s \Gamma1
