title = "Measurements of ultraviolet radiation from a 5-km/s bow shock",
abstract = "Ultraviolet emission from a 5.1-km/s re-entry bow shock was measured in a sounding rocket experiment launched from the Barking Sands Research Range (Kauai, Hawaii) in February 1991 at 14:30 GMT. Optical data were obtained on the downleg portion of the flight as the payload descended from 115 to 62 km in a very shallow trajectory at a nearly constant speed. The intensity of the ultraviolet spectrum (A200-400 nm), and the vacuum ultraviolet resonance radiation emitted by atomic oxygen and hydrogen at A130.4 nm and {\`A}121.5 nm, respectively, were measured. Data from optical instruments in the 200-400-nm spectral region is presented here. Langmuir probe measurements provided data on the total plasma density and electron temperature in the boundary layer over a limited altitude range.",

The design, construction, and calibration of the payload instrumentation involved a collaborative effort among many institutions with Utah State University, Logan, Utah, serving as overall program manager for the instrument package. Utah State University also developed and fabricated the filtered photometers and the atomic oxygen [OI A130.4 nm] and hydrogen [HI A121.5 nm] VUV sensors. The University of Pittsburgh, Pittsburgh, Pennsylvania, developed and fab-ricated the rapid scanning spectrometers and the langmuir microprobe module.
