The lighter outer part of a shadow during an eclipse is called the penumbra. In this region, only a portion of the light source is obscured, allowing some light to reach the area, resulting in a partial shadow. This contrasts with the darker central area known as the umbra, where the light source is completely blocked. As a result, observers in the penumbra experience a partial eclipse.
During a total solar eclipse, the umbra or darkest part of the moon's shadow creates darkness on a small section of the Earth's surface. The penumbra is a part of the moons shadow that is more wide spread and not nearly as dark.
They are the penumbra (think of a large circle) and the umbra (think of a small, darker circle in the center of the large circle). People who have the penumbra only pass over them see a partial eclipse. People who have the umbra pass over them see a total eclipse.
During a lunar eclipse, the Earth comes between the Sun and the Moon, casting its shadow on the Moon. The Earth's shadow has two parts: the outer penumbra and the inner umbra. When the Moon passes through the umbra, it is completely covered by Earth's shadow, leading to a total lunar eclipse.
Lunar eclipse: Earth makes the shadow; the moon passes through it.Earth's shadow is large enough to darken the shole moon at the same time.Solar eclipse: Moon makes the shadow; earth passes through it.Moon's shadow is not large enough to darken the whole earth at the same time ...it causes only a small dark spot, that moves along the surface as the earth turns.
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.
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.
Isay it is penumbra
During a total solar eclipse, the umbra or darkest part of the moon's shadow creates darkness on a small section of the Earth's surface. The penumbra is a part of the moons shadow that is more wide spread and not nearly as dark.
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.
They are the penumbra (think of a large circle) and the umbra (think of a small, darker circle in the center of the large circle). People who have the penumbra only pass over them see a partial eclipse. People who have the umbra pass over them see a total eclipse.
There are actually three identified shadow regions in an eclipse; Umbra, penumbra, and antumbra.The umbra is the region where the light is totally obscured.The penumbra (partially shadowed) is the region of partial eclipse - the light is diminished, but not totally.The antumbra is that rather more distant region in the Umbra, where the light source may be perceived as a circle. A lesser known term.
During a penumbral lunar eclipse, only the outer shadow of the Earth (the penumbra) falls on the Moon's surface. This causes a subtle shading or darkening of the Moon rather than a dramatic change in appearance. It is a more subtle and partial eclipse compared to a partial or total lunar eclipse.

I think you are asking what is the lighter part of the Earth's shadow on the Moon that surrounds the darkest part. The penumbra is this lighter part of the shadow. The darkest part is the umbra.
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.
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.
