In September and October of 1969 we performed an experiment at 6 and 2.8 cm between the 42‐m telescope of the National Radio Astronomy Observatory (NRAO) at Green Bank, West Virginia, and the 22‐m telescope of the Crimea Astrophysical Observatory at Simeis on the Crimea peninsula, USSR. The 8035‐km baseline corresponded to a separation in wavelengths of 135×10 6 and 286×10 6 at 6 and 2.8 cm, respectively. Rubidium oscillators were used at both stations for time and frequency standards, except during the 6‐cm observations when a hydrogen maser was used at Green Bank. The system temperatures for the interferometer were 125° and 210° K at 6 and 2.8 cm, respectively.
