The Proper Motion Survey on plates taken with the Bruce telescope of the Harvard Observatory was begun in 1928 with a fellowship from the Guggenheim Foundation. The plates used have a scale of 1 mm = 59”, generally go down to 16mpg though a few long exposure plates almost reach 18mpg and the survey is considered reasonably complete for the larger motions down to 14.5mpg.
