Here, we report that the north hat and the south hat regions at the high Galactic latitude (|b| >= 30 deg) show anomaly in the power spectrum amplitude around the third peak, which is statistically significant up to 3 sigma. We try to figure out the cause of the observed anomaly by analyzing the low Galactic latitude (|b|< 30 deg) regions where the galaxy contamination is expected to be stronger, and regions that are weakly or strongly dominated by the WMAP instrument noise.
