Abstract
Thanks to the extension of the SOHO mission it is possible to analyze with a good accuracy the dependence of the low-degree p-mode parameters on the solar cycle. We have constructed from the LOI-proxy data (MDI) two time series of 784 days each, one taken at low activity and the other one at high activity. We have focused on analyzing the solar-cycle dependence of the linewidth, the splitting, the asymmetry and the frequency shift of the low-degree p modes. It turns out that some of these parameters exhibit a significant dependence on solar cycle moreover there is also a dependence on m the azimuthal order.
