Broadband photoelectric BVI photometry has been obtained for 56 red stars detected in an objective-prism survey. The magnitude range for the program stars was 8.6 < V < 12.2. The sample contained 33 probable dwarf stars and 21 probable giant stars identified using the (B-V) - (V-I) two-color diagram and two stars of uncertain luminosity class. Distances were derived from photometric parallaxes and used with proper motions obtained from various sources to compute tangential velocities for the probable dwarf stars.
