ABSTRACT
Ultraviolet Coronagraph Spectrometer (UVCS) An ultraviolet spectrometer/coronagraph on board the SOHO spacecraft. The purpose of the UVCS instrument is to locate and characterize the coronal source regions of the solar wind, to identify and understand the dominant physical processes that accelerate the solar wind, to understand how the coronal plasma is heated in solar wind acceleration regions, and to increase the knowledge of coronal phenomena that control the physical properties of the solar wind as determined by in situ measurements.
