Periodic fadings in VHF radio-satellite transmission during the solar eclipse on 23 October 1976

Observations of large magnitude periodic fadings during the solar eclipse of 23 October 1976 are reported. These indicate that the eclipse was associated with the generation of wave disturbances that affected radio-satellite transmissions in the upper VHF. The waves generated had a wavelength of 40 to 700 km and propagated from north to south with a velocity of 556 m/sec. The observations were based on amplitude recordings of VHF radio signals from US Navy Navigational satellites transmitting at 149.988 MHz and a D2-B satellite transmitting at 136.740 MHz. The recording station was at Brisbane. (U.K.)
