Description
During the summer seasons of the years 1977 to 1985 daily velocity
measurements of solar global oscillations have been obtained using a
resonant scattering spectrometer. After calculating the power spectra of
the daily residuals, the mean for each season is found. Several discrete
frequency intervals are defined in the spectrum. The mean power in these
intervals and the cut-off frequency of the p-mode spectrum, determined
for each year, are correlated with the solar activity cycle.
Furthermore, several series of 13 contiguous days for each year are
analyzed.
