Asymmetry of Sunspot Distribution in KAU Solar Observations during 22 and 23 Solar Cycles
ABSTRACT

The King Abdul Aziz University (KAU) solar observations of Sunspot on daily passes from 1981 to 2009 are used to investigate the North-South asymmetry variation of the sunspot numbers and its area. We found that the asymmetry dominated to be southern during the last two solar cycles, which evidently exists following a long-term characteristic time scale. Our results were in compliance with the global asymmetry.
