This Saturday, June 26, was the first lunar eclipse of 2010 happens. Before viewing the first lunar eclipse of 2010, millions of tweens will be in movie theaters taking in the “Eclipse” premiere, the latest installment of “The Twilight Saga,” which promoters have chosen to release on the same date. Saturday’s lunar eclipse will be a partial eclipse and will also visible from much of the Americas, the Pacific and eastern Asia.

This 'moon illusion' experience
The first lunar eclipse of 2010 is going to appear magnified in the U.S. by an effect known as the “moon illusion.” The BBC reports that the eclipse is going to appear larger because it occurs while the Moon is so close to the horizon. The partial lunar eclipse didn't reach totality because the moon, sun and Earth weren't aligned exactly. At its maximum, 54 percent of the Moon’s diameter will be covered at 4:38 a.m. Pacific time. The eclipse should last around three hours.
The rising Moon tricks your brain
If they’re able to stay up until dawn after the excitement of the Twilight Eclipse premiere, tweens will think Saturday’s partial lunar eclipse will look unnaturally large because the human mind perceives the size of the low-hanging Moon in reference to trees, buildings and other foreground objects. Once the moon rises into the sky, it looks smaller without the earthbound objects for the brain to try to compare it to. In reality, a low Moon is the exact same distance away from us as any other moon and doesn’t change in size.
While the Dawn in the in the Americas, Twilight is in Asia
During the partial lunar eclipse, NASA reports that the moon illusion will be particularly strong in western and central parts of the U.S. and Canada where the moon will be setting as the eclipse reaches maximum. Look low and to the west just before dawn according to NASA. On the other side of the world, people in India, Japan, and also many parts of East Asia will see the moon illusion on Saturday evening as the Moon is rising.
For Twilight saga there is a bloody moon
During the lunar eclipse Saturday, the moon will appear the color of blood. But tweens having stayed up all night talking about the Twilight “Eclipse” premiere shouldn’t be alarmed. The reddish hue appears because sunlight reflecting off the moon passes through the Earth's atmosphere, where it is scattered. After the light has passed through the atmosphere, the resulting light is dominated by longer wavelengths the human eye perceives as red. This is the same effect that causes sunsets and sunrises to turn the sky a reddish color.
Cranking up moon telescopes
The first lunar eclipse of 2010 was especially interesting viewed through a telescope. Universe Today suggests cranking up the magnification on your moon telescope to watch particular craters as the shadow sweeps over them. It might remind you of a cloud traveling across a landscape. If you have some kind of eyepiece camera on your moon telescope, try taking some video footage and share it on YouTube. Universe Today gives a chart showing which craters to observe and when to focus on them.
