~July 12th 2014 Full Supermoon in Perigree~

july

On July 12th 2014, the full Moon will appear bigger and brighter, because on this day, the Moon becomes full on the same day as perigee.

This Moon in Perigree is called a Supermoon or Perigree Moon and is the point at which the Moon is closest to the earth, it can appear up to 30% brighter too.

In fact, this summer will bring three “Supermoons”—July 12th, August 10th, and Sept 9th.

The effect is greatly enhanced if you are viewing the Moon near a horizon or through trees and other foreground objects, this effect is called the Moon Illusion.

Moon Illusion: Why the Moon Can Look So Big

Who hasn’t turned down a lane to be confronted by a low, horizon-hugging Moon that seems enormous? This is the famous “Moon illusion.”

Many people assume that this common effect is caused by our atmosphere magnifying the image, but the explanation is far more simple. When the Moon is high overhead, it is dwarfed by the vast hemisphere of the heavens.

By contrast, when the Moon is low, it is viewed in proximity to earthly objects, such as chimneys or trees, whose size and shape provide scale.

Want to make the Moon illusion vanish?

Here’s how to reduce the Moon from enormous to ordinary!

Use a paper tube like the kind that holds paper towels.

Close one eye and look through the tube at the enlarged Moon. It will appear normal.

Now close the eye in the tube and open your other eye. The Moon appears huge again.

Observe the Moon with the tube when it’s high and again when it’s low in the sky. The Moon will appear to be the same size both times.
