güneş lekesi

Güneş yüzeyinin çoğu 5400 santigrat derecelik bir ısıya sahiptir ama büyük güneş lekesinde sıcaklık yaklaşık 4000 santigrat derece düşebilir. - Most of the surface of the Sun has a temperature of about 5400 degrees C, but in a big sunspot the temperature can drop to about 4000 degrees C.

güneş leke

Güneş lekeleri güneş manyetik alanının çok güçlü olduğu Güneş bölgeleridir. - Sunspots are regions of the Sun where the solar magnetic field is very strong.

Güneş lekeleri birkaç bin derece daha serin olduğu için çevrelerinden daha koyu görünür. - Sunspots appear darker than their surroundings because they are a few thousand degrees cooler.

A region on the sun's surface with a lower temperature than its surroundings and intense magnetic activity
Dark colored region on the sun that represents an area of cooler temperatures and extremely high magnetic fields
A dark area on the Sun's surface that is cooler than the area around it Sunspots are caused by magnetic storms on the Sun
An area seen as a dark spot on the photosphere of the Sun Sunspots are concentrations of magnetic flux, typically occurring in bipolar (i e two-part with positive and negative poles like a magnet) clusters or groups They appear dark because they are cooler than the surrounding photosphere
A dark, fringed blemish on the solar surface that is caused by a concentration of the Sun's magnetic field lines See also: Ever-Changing Sun Causes Space Weather
Sunspots are dark cool patches that appear on the surface of the sun and last for about a week. a small dark area on the sun's surface. Cooler-than-average region of gas on the Sun's surface associated with strong local magnetic activity. Sunspots appear as dark spots, but only in contrast with the surrounding photosphere, which is several thousand degrees hotter. Spots several times larger than Earth are visible to the unaided eye (viewed through a filter); very small ones are hard to see even with a telescope. They come and go as part of the solar cycle, usually in pairs or groups, and may last for months; their cause appears to be related to the magnetic field reversals that occur every 11 years. The reality of these apparent flaws in the Sun was generally accepted only 1611. Periods of high sunspot activity are associated on Earth with brighter auroras and interference with radio signals
A cooler region of the Sun's photosphere (which, thus, appears dark) seen as a spot, on the Sun's disc They are caused by concentrations of magnetic flux, typically occurring in groups or clusters The number of sunspots varies according to the Sun's 11 year cycle More sunspots are seen at the Maxima of solar cycles, with few being observed during the Minima between
A small, cooler area on the Sun that shows up as a dark spot on the Sun
an area seen as a dark spot on the photosphere of the Sun They appear dark because they are cooler than the surrounding photosphere
A temporary cool region in the solar photosphere that appears dark by contrast against the surrounding hotter photosphere
A relatively cool, dark area on the surface of the Sun
a magnetic disturbance on the Sun that appears as a dark blotch on its surface
Sunspots are regions where the magnetic field is very strong Sunspots appear darker than their surroundings in almost all kinds of observations because they are a few thousand degrees cooler than their surroundings, and because they are fairly big Sunspots range in diameter between about 1500 miles (2500 km) and more than 30,000 miles (50,000 km) A sunspot is roughly circular in shape, though some are have a very irregular shape Sunspots have two distinct parts: the umbra and the penumbra You can tell a sunspot apart from a pore because a pore has no penumbra Several sunspots can be seen in the full-disk continuum image For more information, see the Sunspots page of Mr Sunspot's Answer Book
  In the photosphere, i e , visible disk of the Sun, a dark marking that manifests a magnetic anomaly that is associated with interference with radio communications on Earth   Note:  Sunspot activity, i e , the number of sunspots occurring at a given time or on a given day, is cyclic   The period of a cycle, from maximum through minimum and back to maximum sunspot count, is approximately 11 years
Dark marking visible on the Sun's surface Although the sunspot temperature is about 4500 K, it appears dark by comparison with the brighter and hotter photospheric background
An intensely magnetic area on the Sun's visible face For unclear reasons, it is slightly cooler than the surrounding photosphere (perhaps because the magnetic field somehow interferes with the outflow of solar heat in that region) and therefore appears a bit darker Sunspots tend to be associated with violent solar outbursts of all kinds
A region on the suns surface with a lower temperature than its surroundings and intense magnetic activity
a cooler darker spot appearing periodically on the sun's photosphere; associated with a strong magnetic field
An area seen as a dark spot on the photosphere of the Sun Sunspots are concentrations of magnetic flux, typically occurring in bipolar clusters or groups They appear dark because they are cooler than the surrounding photosphere
Areas of the Sun's surface that are cooler than surrounding areas The usually appear black on visible light photographs of the Sun Sunspots are usually associated disturbances in the Sun's electromagnetic field
A relatively dark, sharply defined region on the solar disk, marked by an umbra approximately 2000K cooler than the effective photospheric temperature, surrounded by a less dark but also sharply bounded penumbra The average spot diameter is about 3700 km, but can range up to 245,000 km Most sunspots are found in groups of two or more, but they can occur singly Sunspots are cyclic, with a period of approximately 11 years The quantitative description of sunspot activity is called the Wolf sunspot number, denoted R The Wolf sunspot number is also referred to as "Wolfer sunspot number," "Zurich relative sunspot number," or "relative sunspot number "
A dark region on the solar surface where the magnetic field is so strong that the flow of energy from below is suppressed Without this replenishing energy the sunspot cools below the average temperature and appears much darker than surrounding areas, although it would appear bright against a truly dark background
cooler region on the Sun's surface that is a region of intense magnetic fields and is associated with solar activity Because a sunspot is 1000 to 1500 K cooler, it is dimmer than the surrounding surface The number of sunspots is greater when the Sun is more active
{i} relatively cool region which appears as a dark spot on the sun; summer resort (Slang)
an area that appears dark on the photosphere of the sun because it is cooler than the surrounding photosphere; sunspots are concentrations of magnetic flux, typically occurring in bipolar (i e two-part with positive and negative poles like a magnet) clusters or groups; a moderate-sized sunspot is about as large as Earth
An area seen as a dark spot, in contrast with its surroundings, on the photosphere of the Sun Sunspots are concentrations of magnetic flux, typically occurring in bipolar clusters or groups They appear dark because they are cooler than the surrounding photosphere Larger and darker sunspots sometimes are surrounded (completely or partially) by penumbrae The dark centers are umbrae The smallest, immature spots are sometimes called pores
A temporary disturbed area in the solar photosphere that appears dark because it is cooler than the surrounding areas Sunspots consist of concentrations of strong magnetic flux They usually occur in pairs or groups of opposite polarity that move in unison across the face of the Sun as it rotates

sunspots
Darker patches on the solar photosphere; their temperature is around 4000ºC(as against about 6000ºC for the general photosphere), so that they are dark only by contrast; if they could be seen shining on their own, their surface brilliance would be greater than that of an arc-light
