We have studied the temporal variation of power in low-l modes and compared it with solar disk integrated flareindex. GONG power spectrum data for the period of May 1995-December 2001 has been used. Variations in the running mean mode power corresponding to l=0 modes with different radial orders (n = 16,17,...,28) are found to be generally stochastic in nature. A comparison of the temporally varying p-mode power with the disk-integrated flare-index does not show any unambiguous correlations.
