Using 140 years of sunspot area and number data we identify several periodicity in the northern and the southern hemisphere of the sun. Along with 160 day periodicity we found 1-year, 2-year and longer time period periodicity in both the hemisphere. In this poster we show the results of different periodicity observed in the sunspot area and number data of both the hemisphere of the sun. These results could be useful for understanding the underlying mechanisms of the observed periodicity. |
