摘要

Amplitude scintillations of the radio energy from the galactic radio source Cassiopeia A were examined for the total solar eclipse of July 20, 1963, using the 150 foot parabolic antenna at the AFCRL Radio Observatory in Hamilton, Mass. The extent of eclopsing varied along the ionospheric ray path from 100% at about 100 km to about 80% near 500 km. Chart recordings of the amplitude variations of the Cassiopeia A signal were made at frequencies of 29.8, 63, 113, and 228 Mc/s. The extent of variation in amplitude and rate of scintillation was comparable to the extent on control days. Examination of the frequency dependence showed that the scale size of t the irregularities did not change significantly during the eclipse period. No effects in the scintillation records could be uniquely related to the reduction of ionizing illumination and subsequent cooling of the medium. (Author)
