Sunspots are most common during a sunspot (solar magnetic) maximum, this occurs periodically, on an 11 year cycle.
A sunspot is a dark spot on the sun.The number of sunspots changes in cycles of about 11 years.sometimes there are many, and sometimes there are few.
It is often referred t as The Sunspot Cycle - period of about 11 years.
No, sunspot activity increases and decreases. Scientists have observed that the level of sunspot activity follows a cycle of about 11 years (11 years from maximum to maximum and 11 years from minimum to minimum).
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.

The sunspot cycle is about 11 years long. This can vary somewhat; the current cycle has had an extended minimum with very few sunspots for about 3 years, and even now the sunspot numbers are very low for this point in the cycle.
http://en.wikipedia.org/wiki/Sunspot_cycle The definition for sunspot cycle is "the recurring increase and decrease in the number of sunspots over a period averaging about eleven years."
Sunspots are dark, cooler spots on the sun caused by the sun's magnetic field. I believe the cycle between highs and lows of sunspot numbers is 11 years.

Sunspot maximum and sunspot minimum are the points in time (roughly 6 years apart) when the sun is producing the most, or the least sunspots. In the past this has been measured both by sunspot area and sunspot count and is directly tied to the solar magnetic cycle.
The number of sunspots on the Sun seems to fluctuate in an 11-year cycle. When the sunspot cycle is at its maximum, the Sun is typically covered with sunspots. The last "Solar Max" occurred in 2002.We are currently at the "Solar Minimum"; there are very few sunspots. Strangely, the cycle was expected to start rising a year ago, but the Sun seems to be in an extended calm period. In fact, for over 200 days so far this year, there have been no sunspots at all!You can keep track of the sunspot number and see daily photos of the Sun at spaceweather.com.

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.

The sun's pole reversal is tied to the sunspot cycle.
We're not sure why, but when there are very few sunspots during the 11-year "sunspot cycle", or when that cycle slows down, we experience colder than usual weather here on Earth. We've only been tracking sunspots for about 400 years; before then, nobody knew to look for them, or were able to. The sunspot cycle which began last year is Cycle 24. There have been two extended periods of few or no sunspots; one was the Maunder Minimum, from 1645 to 1715, and the Dalton Minimum, from 1790 to 1830. The Maunder Minimum coincides with a period known as the "Little Ice Age", and during the Dalton Minimum the recorded temperatures were perhaps 2-3 degrees below normal. Periods of increased sunspot activities appear to be associated with slightly higher than normal temperatures.
