What do Sunspots do? Best Answer: Sunspots don't really do anything. They are magnetic storms on the Sun, cooler areas on the Sun's surface. They have absolutely no effect of the Earth's weather. Solar flares related to them do affect the visibility of aurora and, in extreme cases, interfere with telecommunications.

Earth Science Brain Honey Final Study Sunspots appear as dark spots on the surface of the Sun. Temperatures in the dark centers of sunspots drop to about 3700 K (compared to 5700 K for the surrounding photosphere). They typically last for several days, although very large ones may live for several weeks.

Sunspots and the rotation of the Sun The sunspots are cooler places on the photosphere, that is the superficial layer of the Sun, where the light that goes out from the Sun forms : they appear, evolve and disappear. The number of spots depends on an 11-years activity cycle of the Sun.

Sunspot Sunspot activity cycles are about every eleven years, with some variation in length. Over the solar cycle, sunspot populations rise quickly and then fall more slowly. The point of highest sunspot activity during a cycle is known as solar maximum, and the point of lowest activity as solar minimum.

Maunder Minimum Maunder Minimum. The Maunder Minimum, also known as the prolonged sunspot minimum, is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time. The term was introduced after John A. Eddy published a landmark 1976 paper in Science.

Sunspot The Wilson effect implies that sunspots are depressions on the Sun's surface. Observations using the Zeeman effect show that prototypical sunspots come in pairs with opposite magnetic polarity.eflecting intense magnetic activity, sunspots accompany secondary phenomena such as coronal loops (prominences) and reconnection events. Most solar flares and coronal mass ejections originate in magnetically active regions around visible sunspot groupings.

Sunspots and Solar Storms At sunspot maximum, the faculae are also at maximum and make the Sun appear slightly (about 0.1%) brighter than at sunspot minimum. Sometimes there are active events called solar prominences associated with sunspots when loops or sheets of glowing gases are ejected from active regions.

Paris Drained 3 Miles of Canal for the First Time in 15 Years and Already Found a Gun Paris: The city of lights and old bikes. City workers in Paris have drained three miles of the Canal-Saint Martin in the city’s trendy 10th arrondissement to refurbish the clogged waterway. It’s the first time the canal has undergone a cleaning since 2001, when 40 tons of assorted junk was removed. So what did they find?

Why do sunspots appear dark? Typical sunspots have a dark region (umbra) surrounded by a lighter region, the penumbra. While sunspots have a temperature of about 6300 °F (3482.2 °C), the surface of the sun which surrounds it has a temperature of 10,000 °F (5537.8 °C).

Pre-Cancers Solar Keratosis/Actinic Keratosis (sunspots) Solar keratosis or actinic keratosis (also commonly known as sunspots) are rough, red, scaly, or crusty spots on the skin that are caused by excessive exposure to Ultraviolet Radiation (UVR) from the sun. They are more common on sun-exposed areas, such as the face, nose, ears, chest, forearms, and back of the hands.

Photosphere: Definition & Features The Photosphere and Sunspots. The visible glowing surface of the sun is more appropriately called the photosphere, and it has a darker edge, called a 'limb.' It's darker because the temperature in the sun's photosphere decreases outward.either the photosphere nor the interior of the sun is solid-it's gaseous instead. A sunspot is a relatively dark spot on the sun with a lower temperature than the other parts of the photosphere. Sunspots occur in places where the magnetic field in the photosphere is many times stronger than average.

- Individual 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 sizes ranging from 16 kilometers (10 mi) to 160,000 kilometers (100,000 mi) in diameter.

Sunspots and climate Sunspots have a diameter of about 37,000 km and appear as dark spots within the photosphere, the outermost layer of the Sun. The photosphere is about 400 km deep, and provides most of our solar radiation. The layer is about 6,000 degrees Kelvin at the inner boundary and 4,200 K on the outside.

The Sunspot Cycle The number of sunspots seen on the  surface  of the Sun changes from year to year. This rise and fall in sunspot counts is a cycle. The length of the cycle is about eleven years on average.

- Sunspots are areas where the Sun's magnetic field is very high. We believe they are dark at the photosphere level (what we see in visible light, generally considered to be the Sun's surface) because they inhibit the convection that transports energy up to the photosphere.

- A 4.3 Mb MPEG movie showing magnetic features in the photosphere over a 36 day period is available here. These data were obtained with the GONG solar telescope network. The movie illustrates the rotation of the Sun as well as the evolution of the Sun's magnetic features-including sunspots.

Is a mini ICE AGE on the way? Scientists warn the sun will 'go to sleep' in 2030 and could cause temperatures to plummet The Maunder Minimum (also known as the prolonged sunspot minimum) is the name used for the period starting in about 1645 and continuing to about 1715 when sunspots became exceedingly rare, as noted by solar observers of the time. It caused London's River Thames to freeze over, and 'frost fairs' became popular.

The Sun Sunlight as we know it-the visible white light, is emitted from the photosphere. The photosphere is one of the coolest regions of the Sun (about 6000 K), and it is here that we can see the granulation caused by the bubbling gas in the convection layer and the sunspots caused by strong magnetic fields.

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.
