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!

What is the sunspot number for each of the days you did research?
You shouldn't be posting your homework questions on WikiAnswers; especially not when the question does not include the relevant information. You can see the daily sunspot numbers on http://www.spaceweather.com.
What is the difference between EDTVs and regular TVs?
An EDTV is different than an HDTV because the picture quality is not the same. EDTV is also known as enhanced definition television and has a maximum resolution of 480p. HDTV is also known as high definition television and has a maximum resolution of 1080p. This means that an HDTV will get better picture quality than an EDTV.
What are the sun spot numbers of the past 100 years?
You can find a chart in the Wikipedia article on "sunspot".
What is the telescope for looking at the sun called?
Usually it's simply called a "solar telescope, but there are other names such as "helioscope" (specialising in sunspot observation).
What is another name for a sunspots?
Sunspots are dark circles on the sun's surface that are cooler than the area surrounding it. Another name for a sunspot is a solar variation or a dark spot.
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.
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.
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 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."
The duration of the sunspot cycle is approximately?
Every 11 years. The entire solar magnetic cycle takes about 22 years; twice in this cycle there is a sunspot maximum.
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 definition of maximum in math?
The definition of a maximum in math is very simple. A maximum is a number that nothing can exceed in that situation.
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.
Where are sunspot found?
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 the largest sunspot?
Prominence Sunspot in 1945
Each peak on the graph represents a sunspot maximum In which years do these maxima occur?
We'll get right to work on that one as soon as we get a look at the graph.
What is an example of a sunspot?
This question makes no sense. It's like asking "what is an example of a pencil?" A pencil is a pencil, and a sunspot is a sunspot.
