Every 11 years. The entire solar magnetic cycle takes about 22 years; twice in this cycle there is a sunspot maximum.

What is the name of the duration relating to the rise and fall of the number of sunspots on the Sun?
It is often referred t as The Sunspot Cycle - period of about 11 years.
Is the shape of a sunspot cycle wavy?
no
When wil lthe next sunspot minimum and sunspot maximum occur after the maximum in 2001and the minimum in 2007?
The last sunspot cycle may have ended in December 2008 (Cycle 23). However, due to lack of sunspot activity, scientist are unsure whether cycle 23 has ended yet, or whether cycle 24 is just starting. A rough guess would place the timing around December 2009 but as with everything, nothing is certain, certainly not the sunspot cycle. (The 11 year cycle is a mean value and cannot be taken as precise). Given the approximate 11-year cycle, and assuming that cycle 24 started in January 2009, then the PEAK of sunspot activity should occur about 5 1/2 years from then, around summer 2014.

What is the character of the sunspot cycle?
You shall have to be more specific if you'd like me to answer.
How would you describe the way sunspot activity changes over the decades and centuries?
We do not yet have a good understanding of the way that sunspot activity changes. We've only been keeping track of sunspots since the early 1600s. In general, sunspot activity increases and decreases in a cycle that is approximately 11 years long. But the cycle isn't particularly stable; for example, the previous cycle, Solar Cycle 23, lasted for closer to 13 years and the current Solar Cycle 24 has been fairly low in activity. This may have long-term significance in our weather here on Earth; twice in the last 4 centuries, we've seen extended periods of very low sunspot activity, and both periods have been associated with unusually cold weather. Some scientists fear that the current sunspot deficit may be a prelude to a new period of cooler-than-normal weather.
How many years is the sunspot cycle?
The sunspot cycle is about 11 years in length.
What is the name of the duration relating to the rise and fall of the number of sunspots on the Sun?
It is often referred t as The Sunspot Cycle - period of about 11 years.
Are you in the high middle or low part of the sunspot cycle?
The Sun is rising close to its high, or peak sunspot cycle.
Is the shape of a sunspot cycle wavy?
no
What occurs in a eleven year cycle?
The cycle of sunspot activity.
What occurs in a eleven-year cycle in space?
The cycle of sunspot activity.
Which solar phenomenon appears in 10- to 12- year cycles?
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.
How long is the sunspot cycle?
11 years in average.
What is the average sunspot cycle in years?
11 years
What is is the sunspot 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."
What are sunspot maximums and sunspot minimums?
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.
How does the sunspot cycle seem to influence life on earth?
