The SOHO Ultraviolet Coronagraph Spectrometer (UVCS/SOHO) is currently being used to observe the extended solar corona between 1 and 10 heliocentric radii. In its first two years of operation, UVCS/SOHO has made spectroscopic measurements leading to the determination of densities, velocities, temperatures, and elemental abundances in coronal holes, equatorial streamers, and coronal mass ejections. Observations of selected non-solar targets, such as near-ecliptic stars, planets, comets, and interplanetary hydrogen and helium, have also produced interesting astronomical results. This poster presents a brief review of the UVCS/SOHO spectroscopic and polarimetric diagnostic capabilities, highlighted by pertinent observational data. Most importantly, we summarize the procedures that have been designed to allow UVCS/SOHO data to be used by a wide array of researchers, and invite participation in this unique investigation.

This work is supported by the National Aeronautics and Space Administration under grant NAG5-3192 to the Smithsonian Astrophysical Observatory, by Agenzia Spaziale Italiana, and by Swiss funding agencies.
