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.
Umbra and penumbra when referred to the moon describes the shadow which is formed when light is blocked from the sun, by the moon. This shadow which falls on the Earth and has two distinct regions; a partially shadowed area which is the penumbra and the centre point a totally dark umbra. We on Earth looking skyward and watching the shadow pass as the Earth revolves would describe the penumbra as a partial eclipse and the umbra as a total eclipse.

The lighter region of a shadow is called the penumbra, which is the area where some light can still reach.
an umbra is the center of the solar eclipse which is the darker part and the penumbra is farther away from the center of the eclipse and is brighter than the umbra
The outer incomplete shadow formed during an eclipse is called the penumbra. This is where the sun's light is only partially blocked by the blocking object, resulting in a partial shadow being cast on Earth.

An umbra is formed when an object blocks all of the light from a light source. A penumbra is formed when light from one source is blocked with light from another source filling in some of the shadow, OR when a large light source is only partially blocked. http://www.learner.org/workshops/sheddinglight/highlights/highlights1.html
A darker area known as an umbra is formed when sunlight is completely blocked. If only partial blocking occurs, a lighter area called a penumbra is formed.

The penumbra landed on the eclipse.
