AbstractThe latitudinal distribution of sunspot groups over a solar cycle is investigated. Although individual sunspot groups of a solar cycle emerge randomly at any middle and low latitude, the whole latitudinal distribution of sunspot groups of the cycle is not stochastic and, in fact, can be represented by a probability density function of the Gamma distribution having maximum probability at about 15.5degrees. The maximum amplitude of a solar cycle is found to be positively correlated against the number of sunspot groups at high latitude (greater than or equal to 35degrees) over the cycle, as well as the mean latitude. Also, the relation between the asymmetry of sunspot groups and its latitude is investigated, and a pattern of the N-S asymmetry in solar activity is suggested.
