What does the 11-year cycle of sunspots correspond to?
LooneyTunerIan
The "11 years" is only approximately; mainly, it is the long-term average. The individual cycles can be quite a bit longer or shorter. It corresponds to the Sun's 22-year magnetic cycle.

What is the definition of sunspot maximum?
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.
Why does the number of sunspots vary?
The number of sunspots depends on the magnetic field of the Sun. This magnetic field changes with a period of roughly 22 years; twice in each of these magnetic cycles there is a maximum of sunspots. (So, the sunspot cycle has a period of about 11 years (on average), whilst the magnetic cycle has a period of about 22 years.)I am not sure whether the reasons for the magnetic cycles are completely understood, but you can check what is known so far, in the Wikipedia article on "Solar dynamo".
How long do sunspots last for?
Sunspots are as long as your dick or vag
What happens to the magnetic polarities of the sunspots when a new cycle begin?
The number of sunspots is constantly changing. The Sun's activity level goes through an 11 year cycle; right now, we are at the minimum of the Sun's activity, and the sunspot number is very low. (In 2008, there were almost 300 days when the sunspot number was zero.) The number of sunspots will probably begin climbing fairly soon, and we can expect the next solar maximum to occur in 2012 or 2013. You can see the sunspot number at spaceweather.com.
What is the fungus on sunspots?
I advise you to see a dermatologist.
Sunspots vary in a cycle that lasts about?
11 years
Sunspots follow a cycle of how many years?
11 years.
Where sunspots form?
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.

What are the cool areas on the sun called?
These are called sunspots. These are the cooler darker areas on the sun.They range in size from 800 to 80000 km in diameter. They have very strong magnetic fields that can affect radio communications on earth. They follow an eleven year cycle called the sunspot cycle.
Short-term changes in climate on earth may related to?
sunspots cycle
What makes the sunspots?
Sunspots are temporary phenomena on the photosphere of the Sun that appear visibly as dark spots compared to surrounding regions. They correspond to concentrations of magnetic field that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.
Are sunspots most common during a sunspot minimum?
Sunspots are most common during a sunspot (solar magnetic) maximum, this occurs periodically, on an 11 year cycle.
How many sun spots are in the sun?
It changes, because sunspots are not permanent and can come and go on a cycle.
What are the dark areas in the photosphere associated with an 11 year cycle?
sunspots... Dark cooler area on the sun often increase during all 11yr cycle
What does a large number of sunspots mean?
A large number of sunspots indicates a high solar activity, which occurs on an 11-year cycle. Electronic communications can seriously be disrupted during this time.
