During a full moon lunar eclipses can occur.
A full moon. For more, go to: http://www.moonphases.info/images/moon-phases-diagram.gif
During an annular eclipse, the Earth passes beyond the umbral shadow of the moon.
Lunar eclipses can only happen when the Moon is EXACTLY full.
This is when the FULL MOON occurs, with the Earth-facing hemisphere fully illuminated.
this is a partial eclipse
Penumbral eclipse
Slightly higher than the ones that occur during First Quarter and Third Quarter,
and roughly the same amplitude as those that occur at New Moon.
If you're in the umbra, you see a total solar eclipse.
A lunar eclipse only happens at the full moon.
A solar eclipse.
The outer portion of the shadow is called the "penumbra".
There are two main shadows that Earth projects; one is called the 'umbra', which is the complete shadow where all direct light is blocked out, the other is the 'penumbra', which is a partial shadow. The effect is similar to standing in front of a light source and seeing both a dark shadow in the middle (the umbra) and a lighter shadow on the outer edge (the penumbra). During this eclipse the Moon will pass through both shadows.
A lunar eclipse occurs when the moon passes through the Earth's shadow. The moon passes behind the earth and prevents the sun's rays from striking the moon. There are three basic types of lunar eclipses: 1. Penumbral Lunar Eclipse - when the moon passes through the Earth's penumbral (outer) shadow. This type of eclipse is very subtle and difficult to notice. 2. Partial Lunar Eclipse - when part of the moon passes through the Earth's umbral (inner) shadow. This type of eclipse is easy to see. 3. Total Lunar Eclipse - then the entire moon passes through the Earth's umbral shadow. The moon turns a red hue. A lunar eclipse can only occur during a full moon when the Sun, Earth, and Moon are aligned with the Earth in the middle.
The "penumbra" or outer shadow is the area of a shadow from which part of the light source, but not all of it, is visible.For a total solar eclipse, the regions where the Moon's shadow only partially covers the Sun is called the penumbra. Areas where the maximum shadow occurs, where the Moon is centered on the Sun, is the umbra. An eclipse where the Moon does not cover the entire Sun is called an annular eclipse, and the shadow area is called the antumbra.
The umbra in a shadow is the portion where light from a source is completely blocked. This is in the middle of the shadow. The area around this, where light from part, but not all of the source shines is called the penumbra. In the shadow cast by the moon in an eclipse, the penumbra is the partial shadow that occurs before the total eclipse, and the umbra is the 'total eclipse' portion
The outer portion of the shadow is called the "penumbra".
it's called the penumbra
It first enters the penumbral shadow, or outer shadow caused by the Sun shining "around" the Earth. For a "partial" lunar eclipse, the Moon eventually but only partly enters the dark red "umbral shadow." If it doesn't, the eclipse is called a penumbral eclipse.

Isay it is penumbra
Umbra is latin for shadow. It's often used for the central part of the shadow of the moon during an eclipse. The outer part of the shadow, or penumbra, still receives some light.

A penumbral lunar eclipse occurs when the moon passes through the Earth's penumbra.
Penumbra, the part outside the Umbra. In the Penumbra you see the sun with a bite taken out of it, but you still get daylight.

A total solar eclipse will block the sun from view and only leaving the Sun's brilliant white edge of the sun. The shadow of the moon is never wider than 275 kilometers.
