Abstract

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 135×106 and 286×106 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.
