Corona around the moon

These colorful rings of a lunar corona appear when we see the moon through a very thin cloud of similarly-sized water droplets.

A few days ago, we ran an image of a pollen sunset that looked similar to this image, but had a different cause. Both images showed the optical phenomenon known as a corona. This lunar corona is from Sergio Emilio Montúfar Codoñer of Buenos Aires, Argentina.

We ran this photo past Les, by the way, and he commented that this rather highly processed image shows brighter colors than what the eye would see.

Moon coronae are rare, and yet more commonly seen than solar coronae, because the sun is so bright. That’s why the pollen corona photo from earlier this month, which showed a corona around the sun, was taken at sunset.

Sergio Emilio Montúfar Codoñer’s image ran as an Astronomy Picture of the Day, last June. Thank you, Sergio, for granting us permission to publish it here.

Bottom line: Photo by Sergio Emilio Montúfar Codoñer of Argentina of a corona around the moon.
