The regression analysis between frequency shifts and activity proxies indicates that the correlation and slopes are correlated and both increase in going from time series of 9 to 108 days. We also observe that the energy of the mode is anti-correlated with solar activity while the rate at which the energy is supplied remains constant over the solar cycle.4 pages, To appear in the conference proceeding of GONG 2008 / SOHO XXISolar and Stellar Astrophysicstext
