How many years is the sunspot cycle?
The sunspot cycle is about 11 years in length.
How is the sunspot cycle directly relevant to us here on Earth?
The 11-year sunspot cycle is not especially relevant to life on Earth, but longer cycles that appear to be connected to sunspots may also have an influence on Earth's climate. For example, in the 300 years that we have been tracking sunspot numbers, we have observed two extended minima of sunspots, the Maunder Minimum of 70+ years and the Dalton Minimum of about 40 years. We do not know precisely what the relationship is between sunspot minima and climate, but in each case the lack of sunspots seemed to be correlated with lower-than-normal temperatures. With our modern electronic technological civilization for the past 80 years, however, another factor may come into play. Peaks of the sunspot cycle are also associated with "solar storms" and higher-than-average levels of geomagnetic activity. This can cause problems with unshielded electronic devices, and a severe solar storm might cause widespread disruption of our satellite-based communications networks. In an extreme case, a massive solar storm might cause the failure of many weather satellites, leading the an inability to predict and track tropical storms or provide communications to military command-and-control systems.
How many sunspots will there be in 2014?
Present indications are that the current Sunspot Cycle is a fairly quiet one, but this is a very variable measure. The number of sunspots is difficult to predict.The sunspot number is not a simple count of individual spots, and the Wolf Number is conventionally used.The expected maximum will probably be a little delayed, based on predictions.The current cycle is known as number 24.By convention, the cycle is considered to repeat every 11 years, but the cycle may be a 22 year one in fact.The spots drift in general, towards the Sun's Equator, or away from it, depending on the latitude (N or S) from the Sun's equator. Sunspots seldom occur beyond 30o from the Equator.
Sunspots follow a cycle of how many years?
11 years.
How long is the solar cycle?
Our star, the Sun, flips its magnetic N and S poles roughly once every 11 years making a complete cycle (back to the start position) a 22 year event. After the poles flip, the Sun enters a "quiet" phase during which there are very few sunspots (called a solar Minimum), while during the time the poles are flipping the number of sunspots increases (called a solar Maximum). More on the process is obtainable form the related link below.
How many years is the sunspot cycle?
The sunspot cycle is about 11 years in length.
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.
The number of sunspots varies in a cycle that lasts how many years?
11 years, on average.11 years, on average.11 years, on average.11 years, on average.
How many years pass between a year of where there are many sunspots to the next period of lower amounts of sunspots?
Sunspot activity increases and decreases with a frequency of about eleven years from peak to peak, so there are about five and a half years from a period of highest sunspot activity to a period of lowest sunspot activity. The last peak was in 2001, so the next peak is expected in 2012.
How many days is a average menstrual cycle?
The average menstrual cycle lasts 28 days, from the start of menstruation to the start of the next menstruation. The "bleeding phase" typically lasts 5-7 days.
How many years is the period of the sunspot?
Individual sunspots can appear and disappear in a single day, or even in just a few hours. On the other hand, some sunspots that disappear as the Sun spins will re-appear 15 days later when the spot becomes visible again. The "sunspot cycle" is typically about 11 years long from peak to peak, but the pattern isn't especially constant. Some cycles take as little as 8 to 9 years, while some stretch out for 15-17 years.
A typical star lasts for how many years?
12 billion years

How many pages does The Day Lasts More Than a Hundred Years have?
The Day Lasts More Than a Hundred Years has 368 pages.
Do solar eruptions have a pattern?
Yes. There is a cycle about 11 years long from the "Solar Minimum" to the "Solar Maximum" to the "Solar Minimum" again. During the minimums, there are few sunspots and not many big flares and eruptions. In 2008, for example, there were 300 days with ZERO sunspots. Today (January 28, 2009) the sunspot number is 11, but for the last week it has been 0. In 5 years or so, we expect the Sun to be very speckled, with sunspot numbers of 300 or more.
How many president terms is 3 years?
