New observations made with instruments aboard Japan's Hinode satellite reveal the hotter outer atmosphere is due to nanoflares.
Nanoflares are small, sudden bursts of heat and energy. "They occur within tiny strands that are bundled together to form a magnetic tube called a coronal loop,"

The atmosphere of the Sun is called the Corona and its temperature reaches over 1-3 million degrees, you would think that at the surface its is where it only reaches 5000º K, that the further away you got the cooler it would be. No-one can explain the phenomena.
The ions leaving the sun are accelerated prior to entering the corona. The accelerated ions have a higher velocity and this higher velocity creates a higher temperature through collisions.
The corona is hotter than the photosphere because the sun's magnetic field carries energy upward from the surface and into the chromosphere and corona. The opposite effect is observed when the magnetic fields cause sunspots to form, resulting in cooler surfaces.
some people say it is 2 million degrees. I'm not really sure though
The Corona is the area around the suns surface that extends out more than a million kilometers, the temperature there can reach two million degrees, it is also where solar wind starts.
is15,000,000oC
The Suns surface is about 6,000K much hotter than the Earths crust. The hottest lava can get at the surface is about 1,400K
The Corona I believe. You should check a diagram of the sun as well.The parts of the sun's atmosphere from the surface outward are the photosphere, the chromosphere, the corona, and the outer layers of the corona called the solar wind. The photosphere is the visible part of the Sun's atmosphere.The parts of the sun's atmosphere from the surface outward are the photosphere, the chromosphere, the corona, and the outer layers of the corona called the solar wind. The photosphere is the visible part of the Sun's atmosphere.the outer layer of the suns atmosphere is the coronathe outer layer of the suns atmosphere is the coronaThe outer mst part of the sun's atmosphere is called the corona.
The corona can be seen only during solar eclipses, when the main radiation from the Sun's surface is blocked by the passage of the Moon or with special instruments. The corona isn't as bright as the other parts of the sun and the solar eclips blocks that brightness.
The corona is.
Hottest Layer of the Suns Atmospere.The core is the hottest layer of the sun. Its temperature is nearly 15 million degrees F.The reason that the core is the hottest is due to the gravitational pressure.This being said, there are individual spots in the corona of the sun which from time to time is known to be hotter than the core. The corona is an outer atmosphere of the sun (if you see a picture of a solar eclipse, the corona is typically the edge of the sun not covered by the earth).
The Suns surface is about 6,000K much hotter than the Earths crust. The hottest lava can get at the surface is about 1,400K
One interesting thing that has been found about the corona is that it's much hotter than the Sun's surface - while the Sun's surface has a temperature of about 6000 K, the corona has a temperature has a temperature around a million K. This obviously can't be caused by regular heat transfer; scientists are still researching exactly how the energy gets from the Sun to the corona.
The suns surface is hotter, estimated to be around 5500-6000 Kelvin.
The corona is hotter than the photosphere because the sun's magnetic field carries energy upward from the surface and into the chromosphere and corona. The opposite effect is observed when the magnetic fields cause sunspots to form resulting in cooler surfaces.

No it is not, however it is similar to that of the sun's surface
You can see Solar Flares in the Suns' Corona. corona (apex)

The sun's corona has a temperature of 1,799,540 to 5,399540 Fahrenheit, which is significantly hotter than solar rays - the Sun's solar radiation is said to have a temperature of about 9980 Fahrenheit.
