How to say "corona" in Japanese

• コロナCommon
  nounThe common loanword and the default choice for most senses of 'corona', above all the sun's glowing outer atmosphere; it is also the word used for the coronavirus.
• 光環こうかん
  nounLiterally a 'ring of light'; a less common word for a corona as a luminous ring, such as that around the sun. コロナ remains the word you will actually want.
• 白光はっこう
  nounIts 'corona' sense is marginal: the word really means white light, and コロナ is the natural choice when you mean a corona.
• 暈かさ
  nounThe word for a halo: a ring of light around the Sun, Moon, and so on. Its 'corona' sense is this atmospheric ring, not the sun's outer atmosphere.
• 金環きんかん
  nounLiterally a 'golden ring'; it matches 'corona' only in the image of a golden ring of light and is seldom the word you want — コロナ is the safer pick.

Use 「コロナ」 as the default for 'corona', especially the sun's; 暈 for a ring of light around the Sun or Moon; 光環 is a less common alternative, while 白光 and 金環 are marginal.
