Lunar eclipse and Moon Illusion

A partial Lunar Eclipse will take place on June 26th. Observers in Canada, the US and East Asia will be able to see the eclipse when the moon is near the horizon when the Moon illusion is also apparent.

The moon illusion refers to the moon seeming larger when it is near the horizon than when it is high in the sky. Some people judge it to be as much as twice as large, but the average estimate is 50% to 75% larger. But this an optical illusion.
