This article deals primarily with secular changes in proper motion, a subject of interest for its own sake but also for the determination of radial velocity, independent of Doppler shift. The effect of the proper motions of background stars is evaluated; the effect of acceleration on orbital motion is discussed. A An illustration of a well-determined secular acceleration is that of Barnard's star; other promising stars are listed. © 1977.
