The LASP-built High-Resolution Ultraviolet Spectrometer measured solar ultraviolet lines between 1050 and 2300 A and their variation with time and position on the disk. Spectro-heliograms were also generated at selected wavelengths. The instrument consisted of an extended-focal-length Cassegrain telescope, an Ebert monochromator, and a small computer. HR UVS flew on the OSO-8 mission, which was the last spacecraft in the OSO series.
