摘要

We present a correlation analysis of GONG p-mode frequencies with nine solar activity indices for the period from 1995 August to 1997 August. This study includes spherical harmonic degrees in the range 2150 and the frequency range of 1500-3500 pHz, Using three statistical tests, the measured mean fre- quency shifts show strong to good correlation with activity indices. A decrease of 0.06 mu Hz in frequency during the descending phase of solar cycle 22 and an increase of 0.04 mu Hz in the ascending phase of solar cycle 23 are observed. These results provide the first evidence for change in p-mode frequencies around the declining phase of cycle 22 and the beginning of new cycle 23. This analysis further confirms that the temporal behavior of the solar frequency shifts closely follow the pliase of the solar activity cycle.
