Abstract
The Penn State Fiber Optic Echelle has been moved to Kitt Peak and works with either the coude feed telescope or 2.1 meter. It is about twice as efficient as the coude Camera No. 5 for similar bandpass at 600 nm and is comparable at 400 nm using the coude feed telescope. The high illumination stability afforded by the fiber is a decided advantage where spectrophotometric and radial velocity stability are at a premium, as in the study of active stars. We are using this instrument to intensively monitor about 10 regular RS CVn systems and about six short period and W UMa systems for a two week period each observing semester.
