Measurements of solar oscillations at 37 GHz.
Abstract
The authors present 37 GHz observations of solar oscillations made during August 1983 and May 1988 at Metsähovi Radio Research Station. Altogether they had data from ten clear days which could be used for further analysis. Five quiet regions were selected from the Sun and the amplitude differencies were monitored during the day. Due to large amount of data only typical examples are presented. During favourable conditions the amplitude at the period of 160 minutes would increase in respect with the other peaks in the power spectrum. The data would also give some suggestions that a higher degree g-mode oscillation 1 ≥ 5 could be possible.
