It's the kind of word that's at the tip of my tongue but I can't quite remember it.

The bright, hazy light around the moon during a total solar eclipse is the sun's ( ).

I've got to fill in that blank. I do remember that earlier it was described as a halo around the sun only visible during a solar eclipse, because normally the bright disk of the sun makes it impossible to see.

please help!

Well, I finally remembered! It was the "Corona". No thanks to you, lol.
=)

corona

Congratulations on remembering the word! Yes, the correct word to fill in the blank is "corona." The corona is the bright, hazy light that surrounds the sun during a total solar eclipse. This phenomenon occurs because the moon covers the main body of the sun, revealing the outer atmosphere of the sun called the corona. The corona is normally invisible to the naked eye because the brightness of the sun's disk overwhelms it. However, during a solar eclipse, the moon blocks the direct sunlight, allowing the corona to become visible.
