Abstract

THE results of our observations of the solar potassium resonance absorption line at 7,699 Å using integrated solar light from the McMath telescope at Kitt Peak together with an atomic beam resonance scattering apparatus are reported here. In two long runs on successive days we observed wavelength oscillations of large amplitude with a period close to 160 min. If, as we believe, these oscillations are produced by motions of the photosphere, they provide evidence for oscillations of the entire Sun. We describe our experimental method, the analysis of the observations, and the results we obtain, and compare these with previous results.
