AB: We present for the first time synoptic maps of the extended solar corona (r/Ro > 1.5) based on eight years of data from the SOHO Ultraviolet Coronagraph Spectrometer (UVCS). The data reveal the changes in the physical properties of the large scale features in the corona. Maps of O VI line intensities, line widths, and line ratios for the O VI 1032/1037 doublet and intensities and line widths for the H I Ly-alpha line reveal information about the evolution of coronal densities, temperatures, and outflow velocities over the solar cycle. In particular these data are used in support of program to understand the solar cycle variation of coronal holes and coronal streamers. This work is supported by NASA Grant NAG5-12781 to the Smithsonian Astrophysical Observatory and NASA subcontract OGSP21010200061SAO awarded to SAO through a grant to Southern Universty at Baton Rouge.
