Sunspots are most frequent about 30 degrees north or south of the equator. They tend to appear there around the maximum of the 11 year sunspot cycle. Earlier in the cycle they areseen at higher latitudes and later they are at lower latitudes.
What is true about sunspots
Sunspots are structures commonly found in the photosphere of the Sun. These dark regions are caused by magnetic activity and are cooler than the surrounding areas, hence appearing dark against the brighter photosphere. Sunspots often occur in pairs with opposite magnetic polarities.
Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
The most observable phenomena in the solar cycle is the variation in the number of sunspots. Sunspots are dark areas on the Sun's surface that represent intense magnetic activity and are closely related to the overall activity level of the Sun. The number of sunspots follows an 11-year cycle, where the Sun goes from a solar minimum with fewer sunspots to a solar maximum with increased sunspot activity and then back to a minimum.
Sunspots are known to be magnetic phenomena because they are areas on the Sun's surface where the magnetic field is significantly stronger than in surrounding regions. This causes a suppression of convection, leading to cooler temperatures and darker spots on the solar surface. Sunspots often appear in pairs, with one spot having a magnetic field oriented in one direction and the other in the opposite direction.
There is a solar phenomenon believed to be affected by an increase in sunspots. Most solar flares are believed to be linked to an increase in sunspots.
no, most do
No. Sunspots are only found on the Sun.
Sunspots are most common during a sunspot (solar magnetic) maximum, this occurs periodically, on an 11 year cycle.
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.

It was Galileo who first studied the dark spots found in the Sun which are now referred to as sunspots. It is believed that the intense magnetic fields surrounding the sun cause the appearance of sunspots.

The most discernable features on the Sun are sunspots; areas that are a little cooler, and therefore a little darker, than the rest of the Sun around them. We know that sunspots are formed by intense magnetic regions, and that large solar flares and prominences are associated with sunspots. There's a cycle of increasing and decreasing numbers of sunspots that runs about 11 years in length, although this can vary by a couple of years. Slower cycles seem to be correlated with fewer sunspots, and faster cycles with more sunspots, but scientists don't have a detailed explanation for why the cycle exists, or why it is 11 years (more or less) in length. We are currently (in 2014) at or near the maximum of the sunspot cycle. You can see the daily view of the Sun and yesterday's sunspot number at the SpaceWeather website, www.spaceweather.com.
