I'm not exactly sure what you are asking but the sun is visible everyday! Just look up. During a Total Solar eclipse however the outer atmosphere of the sun known as the corona is visible. This is the only time that it can been seen (with the naked eye) from earth.
The outer layers of the Sun, the "corona", are normally visible only during a total eclipse, because the brightness of the Sun itself would blind you from being able to see the corona.
However, a special telescope called a "coronagraph" was invented in 1930 to allow scientists to create their own artificial eclipses by blocking the direct rays of the Sun, and allowing the corona to be seen.
The corona is the is the correct answer
Only the Corona (The outermost Layer.)
this is infact how the first studies of sunspot and Coronal Mass Ejections were carried out.
during a total solar eclipse, only the corona is visible..... i think
That's the 'Corona' - it shows as a bright 'halo' around the darkened moon's disc.

The outermost layer of the sun is the corona. Only visible during eclipses, it is a low density cloud of plasma with higher transparency than the inner layers.
The next total solar eclipse will be on July 22, 2009. It will be visible from northern India through China. The next total solar eclipse visible in the United States will be on August 21, 2017. It will be visible from Oregon through South Carolina, but in Georgia it will be only visible as a total eclipse in the very northeastern corner of the state. Much of the rest of the USA will see a partial eclipse. The next total eclipse visible in the southern part of Georgia will be on March 30, 2052.
The corona on the Sun is the plasma aura that surrounds the Sun. It extends millions of kilometers into space and has extremely high temperatures.

That would be the Sun's Corona.

The solar corona, or upper atmosphere, is only visible during a solar eclipse.

Technically, the statement is "True", but it is misleading. The statement implies that the corona is 'usually' visible, and is still visible during a solar eclipse. Actually, the corona is almost always drowned out by the glare of the sun, and is visible 'only' during a total solar eclipse, or with the disk somehow obscured with some astronomical research device.
no only in certain areas
