The sunspot active longitudes for solar cycle No. 22.
Abstract
The active longitudes of the sunspot total areas (240 - 200° N, 160 - 120° N, 40 - 0° N; 120 - 80° S, 40 - 0° S) and the numbers of large sunspot groups (360 - 320° N, 120 - 80° N, 40 - 0° N; 280 - 240° S, 120 - 80° S, 40 - 0° S) are detected for the solar cycle No. 22. The coincidence of most sunspot active longitudes in solar cycles No. 21 and No. 22 and their significant N-S asymmetry are revealed. Indices of concentration in sunspot active longitudes Ck(NLg) and KCk decrease from cycle No. 21 to cycle No. 22.
