Outer layer of the sun (6)

I believe the answer is:

corona

(Other definitions for corona that I've seen before include "Ring around the sun" , "Trumpet" , "Circle of light around sun or moon" , "Circle of light around the sun during an eclipse" , "Glow around the sun" .)

I've seen this clue in the Universal.
