At a total solar eclipse.
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.
You can see the corona and chromosphere.
Photosphere is what we see most of the time, but you can also see the Chromosphere during a solar eclipse.
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.
That is the "Chromosphere."
chromosphere
The chromosphere of the sun is visible during a total solar eclipse when the moon blocks the bright photosphere, allowing the fainter chromosphere to be observed. It appears as a reddish ring around the dark silhouette of the moon. Outside of a total solar eclipse, specialized solar observing equipment is needed to observe the chromosphere safely.
It is not true, there will be no two suns, only one. But we can see the sun in two places simultaneously on 21 June 2010
The is only one Sun in the Martian sky, the same one you see from Earth.
The best way to observe the Sun's chromosphere and corona is through specialized instruments such as solar telescopes equipped with filters that isolate specific wavelengths of light. For the chromosphere, H-alpha filters are commonly used, allowing astronomers to see the dynamic features like prominences and solar flares. The corona can be observed during a total solar eclipse, where the Moon completely obscures the Sun's bright disk, or through the use of coronagraphs that artificially block the Sun's light. These methods provide valuable insights into solar activity and the Sun's magnetic field.
