Take a look at this image. It shows the Sun’s equator, north pole , south pole , and lines of longitude and latitude .
Surprisingly, almost all sunspots are found in two bands on the Sun, just north and south of the equator. At the start of the cycle, the sunspots appear at latitudes of about 30 degrees, both north and south of the equator.
Then, as the cycle continues, more appear at lower latitudes until, at the end of the cycle, most spots appear near the equator.
If you plot each sunspot's latitude (Y-axis) against the date when it first appeared (X-axis) you get the diagram below
