I guess you mean only during a total eclipse of the Sun. At that time we can see the chromosphere and the corona. The outermost layer is the corona.
At a total solar eclipse.
The photosphere, the chromosphere, and the corona
The sun's atmosphere, or the chromosphere and the corona, can be seen with the unaided eye only during a total solar eclips.
You can see the chromosphere during a total solar eclipse when the moon fully blocks the bright solar disk, revealing the reddish layer of the sun's atmosphere.
The chromosphere can be seen during a total solar eclipse when the moon completely covers the sun, revealing the sun's outer layers. Outside of an eclipse, it is not typically visible due to the brightness of the sun's photosphere overwhelming it.
The pink layer of the sun is the chromosphere. This layer is located above the photosphere and is characterized by a reddish-pink color during solar eclipses. The chromosphere is responsible for emitting the solar prominences and solar flares seen during solar events.
the chromosphere glows because of the release of hot, low density gases that are emitted from the sun. Normally, it can't be seen by the naked eye due to light from the photosphere blocking it. During a solar eclipse, the chromosphere is visible, appearing as a red ring around the Sun.
The bright red layer of the sun's surface containing hydrogen gas that can be seen is called the chromosphere. It lies just above the sun's visible surface, the photosphere, and is responsible for the red color seen during solar eclipses.
