Abstract:
In this paper, we present a correlation study of nine solar activity indices with p-mode frequency shifts obtained from the GONG data. It is found that the two are closely correlated and a linear relationship exits. Further, the GONG p-mode frequencies for the period 1995 August to 1997 August show that the mean frequency decreases by 0.06 μHz during the descending phase of the solar cycle 22 and increases by 0.04 μHz in the ascending phase of the new solar cycle 23.
