Sunspots are regions on the solar surface that appear dark because they are cooler than the surrounding photosphere, typically by about 1500 K (thus, they are still at a temperature of about 4500 K, but this is cool compared to the rest of the photosphere). They are only dark in a relative sense; a sunspot removed from the bright background of the Sun would glow quite brightly. Some sunspots are as large as 50,000 miles across, and they move across the surface of the sun, contracting and expanding as they go.
The sun has a magnetic field that is twisted around inside the Sun as it spins. There are places on the sun where this magnetic field rises up from below the sun's surface and pokes through, creating sunspots. Sunspots are magnetic and often have a north and south pole like a magnet. They come and go over the surface of the Sun and last from a few days to a few weeks. The period of time between maximum outbreaks of sunspots is about 9 to 14 years, with an average of 11 years. A link can be found below.

∙ 11y agoThey look like small, dark spots on the sun.
The reason they're so hard to see, and that most people have never seen them
and don't know what they look like, is that most people are smart enough to listen
to the warnings never to look directly at the sun, knowing that if you do, it could be
the last time you ever 'look' at anything. So you really need to get clever about it,
and rig up some kind of equipment or system of examining details on the sun.

∙ 9y agoSunspots appear as dark areas on the sun that are cooler then the surrounding areas. They are caused by increased magnetic activity. Sunspot activity is describing increased sunspots on the suns surface.

∙ 12y agoA dark patch on the surface of the sun. Sunspots usually occur in clusters and last about two weeks. The number of visible sunspots fluctuates in an eleven-year cycle. It has been suggested that the sun is 1% cooler when it has no spots, and that this variation in solar radiation might affect the climates of the earth.
They have no effect really. But it does put earth in the line of fire because that's when it is its most dangerous due to that it has a much higher rate of a solar flare.
Sunspots are cooler, darker areas of the sun that come and go every so often. I think they can interfer with earth's magnetic field.
Sunspots do not affect the קראי directly, but they are an indication of the Suns strength. In the 17th century there was the "little ice age" during which the River Thames in London completely froze and extremely low temperatures were recorded worldwide. At that time almost no sunspots were seen on the Sun.

∙ 11y agoSunspots are burned out spots on the surface of the sun that make it cooler, the sunspot CYCLE is the 11.5 years where sunspot amounts change. The first year in the cycle is when the sun has the least amount of sunspots, this is when it is hottest. the middle of the cycle (about 5.25 years through the cycle) is when there are the most sunspots.

The safest way to see sunspots is to visit one of the many astronomy web sites that post photos of the Sun each day; spaceweather.com is an excellent one, and solarcycle24.com is another excellent resource.

How does corona look like?
The Sun's corona is sort of the "atmosphere" of the Sun, a large layer of faintly glowing gaseous material surrounding the Sun. We normally cannot see the corona at all, because the Sun itself shines so much more brightly than the corona does. But when the Moon blocks our view of the Sun itself, during total solar eclipse, we can see the thin, wispy glowing shell around the Sun, and get a view of some of the prominences and streamers that are part of the Sun's "weather". Once we knew what to look for, it was relatively straightforward to invent the coronagraph, a telescope with a solid disk blocking the Sun itself, and producing its own artificial eclipse.
When you look at the sun what motion makes the sun look like its rising and setting?
it makes the sun look like the sun is rising because were actually moving up then the sun looks like it is rising
What is the darkened area of a sunspot is a .?
A sun spot
When the sun passes directly overhead in the tropics - does the sunlight only fall on one specific spot and does the sun still 'look' overhead 20 miles from that spot?
The Sun shines on half of the Earth. If the Sun is DIRECTLY above a certain spot, the sunlight is shining straight down, and the object won't cast any shadow. Someplace 20 miles away, the Sun isn't STRAIGHT up; it's about an arc-minute away from being STRAIGHT up. But you won't be able to tell this without some pretty precise instruments, so it will still "look" like it's overhead. A few minutes earlier or later, and the Sun wouldn't look straight up either.
