Question: Answer: The amount of magnetic flux that rises up to the Sun's surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average. This cycle is sometimes referred to as the sunspot cycle.

Solar flare The frequency of occurrence of solar flares varies, from several per day when the Sun is particularly active to less than one every week when the Sun is quiet, following the 11-year cycle (the solar cycle). Large flares are less frequent than smaller ones. solar flare is a sudden flash of brightness observed near the Sun 's surface.

Earth's location in the Universe The average diameter of the orbit of the Solar System relative to the Galactic Center. The Sun's orbital radius is roughly 8,600 parsecs, or slightly over half way to the galactic edge. One orbital period of the Solar System lasts between 225 and 250 million years.

- solar surface. Solar rotation is one of the principal factors affecting the roughly 11-year cycle of sunspot activity, solar flares, and other phenomena. In the 1860’s Richard Christopher Carrington used sunspots to determine that the period of rotation of the Sun depends on latitude. Spots near the equator of the Sun go around every 25 days, while spots near latitude 45 go around once every 28 days. This so-called differential rotation would not be possible if the Sun were a solid body.

How long does a Sunburn Last? The physical symptoms of sunburns usually disappear in 2 days to a few weeks depending on the severity of the condition. However, its effects tend to last for a lifetime.Excessive sun exposure can result in premature aging, wrinkling, age spots, and other changes that are permanent.

Aurora Borealis: What Causes the Northern Lights & Where to See Them At the center of the sun, the temperature is 27 million degrees Fahrenheit (15 million degrees Celsius). As the temperature on its surface rises and falls, the sun boils and bubbles. Particles escape from the star from the sunspot regions on the surface, hurtling particles of plasma, known as solar wind, into space. It takes these winds around 40 hours to reach Earth.

Sunspots/Solar Cycle Sunspots/Solar Cycle. Sunspots are dark regions on the Sun. They are regions of intense magnetic field that are intimately associated with solar flares and coronal mass ejections.Sunspots appear dark on the sun’s surface because they are cooler (3700 K) than the rest of the solar surface (6000 K).Sunspots are cooler because their intense magnetic fields inhibit the rise of heat from the solar interior. Sunspots can appear alone, or in close connection to other sunspots.Sunspots that are clearly connected to each other are grouped into active regions with an official number designated by NOAA. Active regions are classified according to their size and complexity with a scale known as the modified Zurich scale.unspots can appear alone, or in close connection to other sunspots.

The Orbit of Saturn. How Long is a Year on Saturn? Because of this, the speed with which it orbits the Sun is also considerably slower. As a result, a single year on Saturn lasts an average of about twenty-nine and a half years. And during that time, some interesting changes happen for the planet’s weather systems. Orbital Period:

Sunspot Cycle The sunspot cycle is generally known to be a cycle of approximately 11 years between successive peaks in sunspot activity. What is less known and understood is that with each successive 11 year peak, the magnetic field of the sunspots is reversed.

- The sun and other stars do show periods of slightly higher than normal activity, detectable in our sun by an increase in sunspot activity. During sunspot activity, more energy reaches the Earth. The sun spends about a quarter of its time in a state with very few sunspots.

- The Sun is so hot that when it dies, it will take a long time to cool off. The Sun will die in about 5 billion years, but it will still glow for many billions of years after that. As it cools, it will be what is called a white dwarf star. Eventually, after billions, maybe even trillions of years, it will stop glowing.

Sunspots Sunspot activity — the number of spots on the Sun at any one time — varies with a period of about eleven years. This corresponds to the period of an overall solar-activity cycle whose other features include solar flares and prominences.

Space Weather FAQ (Frequently Asked Questions) Conditions can be mild one minute and stormy the next. On longer time scales, space weather varies with the solar cycle. The solar cycle is an average 11 year cycle where the number of sunspots goes from very few per month, to many, and back to very few. At solar minimum, we might see no sunspots where at solar maximum, we can have 200 sunspots in a month.

Sunspots and Solar Storms Sunspots and Solar Storms. Galileo was the first to study dark spots on the Sun which we call sunspots. They typically measure about 10,000 kilometers across, which makes them on the order of the size of the Earth. They often occur in groups, and come and go. At some times the Sun has hundreds of sunspots, while at other times it may have almost none. Individual spots may last from 1 to 100 days.

What do Sunspots do? sunspots are darker patches on the solar photosphere. their temperature is around 4000 degreesC. a large sunspot consists of a central darkish area or umbra, surrounded by a lighter area of penumbra which may be very extensive and irregular. sunspots tend to appear in groups and are associated with strong magnetic fields. they are also associated with solar flares. they are most common at the time of solar maximum, approx. every eleven years. no sunspot lasts for more than a few ...

- 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 flux that inhibit convection and result in reduced surface temperature compared to the surrounding photosphere.ndividual sunspots may endure anywhere from a few days to a few months, but eventually decay. Sunspots expand and contract as they move across the surface of the Sun with a size ranging from 16 kilometers (10 mi) to 160,000 kilometers (100,000 mi) in diameter.

Main Sequence Stars Lifespans for main sequence stars have a vast range. Whilst our Sun will spend 10 billion years on the main sequence, a high-mass, ten solar-mass (10 M Sun) star will only last 20 million years (2.0× 10 7 years) on the main sequence. A star with a only half the mass of Sun can spend 80 billion years on the main sequence.

- Since most sunspot groups have, on average, about ten spots, this formula for counting sunspots gives reliable numbers even when the observing conditions are less than ideal and small spots are hard to see.

How long does a sunspot cycle last? a full sunspot cycle lasts approximately 22 years. It is usually discussed as the 11 year half-cycles though. It will take quite a few more years of observation before we can determine if there is any larger pattern in the cycles.
