The Solstice Moon Illusion

Posted: Updated:
TRI-CITIES, Wash.--No magic, only human perception.

It's called a Solstice Moon Illusion. To the eye, you might think the moon is really close to Earth.

But it's actually what astronomers say is hugging the horizon.

There's alot of different theories about what causes the illusion.

One astronomer KNDU talked to on Wednesday (June 18th) says the illusion usually happens two days before the start of Summer.

"Tonight with the moon rising so far south, it's almost as if the moon is going to be always sort of low," says Ken Swanson, Astronomer, Rattlesnake Mountain Observatory. It's gonna get up, but normally not as very high as it normally would."

Swanson says its likely we won't see another moon illusion for five to seven years.
