Where do sunspots sit on the Sun?
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin.
What causes sunspots on the surface of the Sun?
Sunspots are caused by disturbances in the Sun’s magnetic field welling up to the photosphere, the Sun’s visible “surface”. The powerful magnetic fields in the vicinity of sunspots produce active regions on the Sun, which in turn frequently spawn disturbances such as solar flares and coronal mass ejections (CMEs).
Are sunspots on the Sun hot?
Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. The temperature of a sunspot is still very hot though—around 6,500 degrees Fahrenheit!
Are sunspots shadows on the surface of the Sun?
Sunspots are irregularly shaped dark regions in the photosphere of the Sun such as the one in the image above. They have an inner dark area called the umbra, and a brighter edge region called the penumbra. Although these terms are the same as the ones used to describe eclipses, sunspots are not shadows.
What do sunspots look like on the Sun?
What do they look like? Sunspots appear as flat, darker patches of skin (tan to dark brown) that are found on areas of the body that have experienced high levels of sun exposure such as the face, shoulders, hands, chest, and the backs of hands.
How hot are sunspots?
But as Fisher points out, sunspots are actually quite hot. “Instead of being about 5700 degrees kelvin like the rest of the photosphere, the temperature of a sunspot is more like 4000 degrees kelvin. But that is still very hot, compared to anything here on the earth.”
Why do sunspots move?
As the sunspots are a result of magnetic processes in the Sun, they move in the direction of its magnetic field lines. As shown in Figure 9 the Sun’s magnetic field lines are extended parallel to the Page 14 equator and become twisted. Therefore, sunspots move mainly parallel to the equator.
How many sunspots are on the Sun?
At Solar Maximum, there will be up to 200 sunspots on the Sun at one time.
Are sunspots hotter or cooler than the Sun?
Sunspots appear dark (in visible light) because they are much cooler than the rest of the surface of the Sun. However, even though they appear dark, they are still very hot.
Do sunspots itch?
These dark spots on the skin are not painful, itchy or harmful, but if you have a lot of sunspots, it’s an indication that you’ve had a lot of sun exposure throughout your lifetime.
Are there sunspots today?
This page is updated daily and the sunspot images every hour….Today’s Sun.

How are sunspots plotted?
Sunspots usually come in pairs and drift from the high latitudes of the Sun toward the equator. When sunspots are plotted according to their latitude and longitude, a very clear “butterfly pattern” develops within each cycle of approximately 11 years.
Where are sunspots located on the Sun?
Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere.
What are sunspots and how are sunspots formed?
Sunspots are temporary phenomena that occur on the Sun’s photosphere which appear as spots darker than the areas surrounding it. These regions reduce the surface temperature which are caused by concentrations of magnetic field flux and inhibit convection. Sunspots usually appear in pairs of opposite magnetic polarity.
Why does the Sun have spots?
Sun spots are areas of damaged skin that occur as a result of your body’s defense mechanism against the sun. When exposed to UV rays, your skin produces more pigment (melanin), making it darker.
Where are the sun spots?
Sunspots and Solar Flares Sunspots. Sunspots are areas that appear dark on the surface of the Sun. Solar Flares. The magnetic field lines near sunspots often tangle, cross, and reorganize. Effects of Solar Activity on Earth. When charged particles from a CME reach areas near Earth, they can trigger intense lights in the sky, called auroras.
