With the sun as a source, scintillations at four microwave frequencies were observed for 1 year. Scintillation was a daily occurrence at sunrise at elevation angles from 1.5° to 7°. This observation indicates the continued presence of point sources on the sun during the peak of the sunspot cycle. It also suggests that the peculiar terrain configuration along the propagation path is conducive to the production of irregularities in the troposphere. Scintillation data can provide information about the troposphere and about the spectrum of the slowly varying component of solar emission.
