We present a summary of our recent efforts to automate the operation of the Dominion Astrophysical Observatory's 1.2-m telescope located at the Herzberg Institute of Astrophysics in Victoria, BC. This telescope is used almost exclusively for the acquisition of stellar spectra with the McKellar coudé spectrograph, configurable with a variety of gratings and cameras to provide resolutions up to R=40,000. In recent observing quarters approximately 30% of the time allocated on the telescope has been conducted robotically on a shared-risk basis. Automatic operation is currently limited to targets brighter than V 7.5. Anticipated improvements include installation of a more sensitive acquisition and guiding CCD to permit operation to V 10, an increase of the wavelength coverage and maximum resolution with the acquisition of new CCD's, pipeline processing of the acquired spectra, and the capability of providing radial-velocity measurements. We present some recent examples of spectra and radial velocities acquired automatically. Programs consist of lengthy time series for single targets to survey programs observing many stars. We encourage submission of proposals by any interested astronomers.
