The Distribution of Sunspot Groups on Solar Disk in the Recent Three Cycles
A latitude distribution of sunspot groups is given by using the data of the visual sunspot observations made at the Yunnan Observatory.From the statistics of the latitude distributions for large area sunspots in the 19th,20th and 21th Cycles some interesting results are derived.
