主　　题：Sun: sunspot   Sun: active cycle   Sun: activity 

摘      要：With the use of the Royal Greenwich Observatory data set of sunspot groups, an attempt is made to examine the north-south asymmetry of solar activity in the extended solar cycles. It is inferred that the asymmetry established for individual solar cycles does not extend to the extended cycles.
