The cycle of maximum and minimum solar activity, known as the solar cycle, typically repeats approximately every 11 years. During this cycle, the sun undergoes periods of increased sunspot activity (solar maximum) and decreased activity (solar minimum). The duration can vary slightly, ranging from about 9 to 14 years. This cycle influences solar phenomena, including solar flares and coronal mass ejections.
every eleven years lol
The moon phases repeat approximately every 29.5 days, which is known as a lunar cycle or lunar month. This cycle includes the full moon, waxing gibbous, first quarter, waxing crescent, new moon, waning crescent, third quarter, and waning gibbous phases.
As 1964 was a leap year, it does not repeat very often. It repeated in 1992 and in the rest of this century it will only repeat in 2020, 2048 and 2076.
Sunspots occur in a cyclic pattern, with the number of sunspots reaching a maximum approximately every 11 years. This period of high sunspot activity is known as the solar maximum. Conversely, the period of minimum sunspot activity is known as the solar minimum.
it doesnt stop
About 11 years on average - but there are large variations in the length of individual cycles. Once each sunspot cycle, the magnetic field on the Sun reverts - so the real (underlying) cycle is about 22 years. (It takes two sunspot cycles for the magnetic field to go back to the original position.)
It is often referred t as The Sunspot Cycle - period of about 11 years.

It would be quite unusual to see auroras as far south as Kentucky, but it has happened; at the peak of the last sunspot cycle, there were auroras in Florida!
The sun's magnetic poles flip approximately every 11 years, coinciding with the sunspot cycle. This phenomenon is known as solar magnetic field reversal.
every eleven years lol
Period can be used in several ways. In math and science, it refers to how often a wave or trigonometric function repeats its action; in oceanography, how often the tides raise and lower; in Biology, part of the menstrual cycle involving the flushing of the uterine lining and egg; in schools and study, a section of the day in which one subject in particular is studied for around an hour; in grammar, it is the end of a sentence; in astronomy, the time between the repeat of certain actions such as sunspot and flare activity. There are many other uses which occur less often.
Magnetic field lines.
You really shouldn't be looking for the answer of a test or homework on the computer. But the answer is How often a wave occurs is the waves frequency.
Scientists often repeat one or more steps several times
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.
