The long range program of the Sproul Observatory initiated in 1937 by P. VAN DE KAMP has been primarily devoted to a detailed astrometric study of the positions of nearby stars from photographs taken with the 24-inch refractor. By now there are 30 years of observations on most stars with parallaxes greater than + O″10 and brighter than the 12th magnitude which are observable at latitude +40°. It follows therefore that there are long series of photographic records of many red dwarf stars.
