Aims. Northern and Southern sunspot activities demonstrate striking synchronous behavior during a solar cycle. But sometimes synchronization fails and the north-south asymmetry occurs. The problem is the origin of the north-south asymmetry and its quasi-regular oscillations. Methods. We employed Cross-Recurrence Plot analysis to extract synchronization between the Northern and Southern sunspot activities. Results. By using Cross-Recurrence Plot technique and extracting line of synchronization
