We present the first far-ultraviolet spectra of a solar-type star in the Arcturus moving group, HD 199288, observed with the newly installed Cosmic Origins Spectrograph (COS) on the HST. The Arcturus moving group was first identified by Eggen as a group of stars orbiting the Galactic center with a speed that is 100 km/s slower relative to the Local Standard Rest. These stars are metal poor ([Fe/H] -0.6) and have peculiar alpha element abundances. They have been recently suggested to be captured from a disrupted satellite of our Galaxy. We analyze the moderate-resolution (R 20,000) spectra to provide new information on the abundances and discuss how the metal-poor nature affects the outer atmospheres of these stars.
