The Investigator conducted basic astronomical research involving interferometer and micrometer measurements of double stars during the period of performance, June 1951 to September 1951. Measurements of double stars were actually performed on 51 nights. Altogether 187 separate positive measurements were made on 75 different stars. In addition, 58 negative or uncertain observations were made on these same stars, and about 17 negative or uncertain observations of 11 other stars. Thus, in total, 262 observations were made of 86 different stars.
