With funding from the National Science Foundation Major Research Instrumentation program, plans are underway for designing, constructing, and fielding an echelle spectrograph patterned after the HIRES instrument on the 10-m Keck I telescope on Mauna Kea. Sky spectra from this and other large telescopes have revealed many new and interesting features in the terrestrial nightglow [Cosby et al., 2006; Cosby and Slanger, 2007; Sharpee et al., 2005; Slanger et al., 2003; Slanger et al., 2006; Slanger et al., 2004; Slanger and Osterbrock, 1998], and we have concluded that full access to such an instrument, with the ability to relocate it at various sites, will have a major impact on the study of the upper atmosphere. CESAR features f/1 camera optics, CCD detection with a range of 310-1040 nm, a resolution of 20,000, and simultaneous photon accumulation over 500 nm. The anticipated sensitivity is 3 photoelectrons R-1 s-1. After commissioning in Alaska, the instrument will become available as a community facility for qualified researchers with particular interests in studying the atmosphere at high spectral resolution, with simultaneous data collection over a broad spectral range. -------------- Cosby, P.C., B.D.
