Abstract
Changes in the internal structure of the Sun over the 11-year magnetic activity cycle could be reflected in the eigenfrequencies of the acoustic p-modes. The first tentative experimental evidence was presented in 19841 and subsequently an analysis of ACRIM solar intensity data2 suggested a decrease of frequencies of the 5-min solar p-modes between 1980 and 1984 of ∼0.4 μHz. Recently3–6 further experimental data have provided conflicting results; frequency increases, decreases and stability have all been reported.
