Are the number of sunspots on the sun's surface always the same?
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).
What is a sunspot and the pattern that exists in the number of sunspots that are observed?
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.
What is the number of years between periods of sunspot activity?
11 years
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.
Sunspots are associated with a brief outburst called what?
Solar flares and coronal mass ejections. You can see the daily sunspot number, and movies of interesting CMEs and flares, at spaceweather.com.

What is the lowest sunspot number?
Sunspots are a cyclical phenomena. The lowest would be zero.
What is a sunspot and the pattern that exists in the number of sunspots that are observed .?
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.
Are sunspots the same size?
No. Some sunspots are fairly small, compared to the size of the Sun, while some can get pretty big. Sunspots grow, and merge, and a "medium" sized sunspot covers an area larger than the Earth. You can see the daily sunspot number on the web at www.spaceweather.com.
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."
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.
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.
What is the number of years between periods of sunspot activity?
11 years
How much sunspots are there on the sun during the peak of the sunspot cycle?
At a minimum, there are no sunspots at all, and the Sun can remain spotless for months at a time. In 2009, for example, there were 260 spotless days. In 2008, there had been 200 spotless days - by September! This last solar minimum lasted for about 18 months longer than is "normal", whatever "normal" is. Since December 2009, the Sun has slowly become more and more active, with at least a few sunspots visible almost every day since then. The Solar Maximum in 2004 was QUITE active; the Sun looked freckled!
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.
Could the number of sunspots affect the amount of volcanic activity on earth?
Highly unlikely.
