People in the penumbra of the Moon's path during an eclipse see only a very slight, partial eclipse. There are three types of lunar eclipses, and depending on where you are in the world during an eclipse event, you may see one of these variations. The first type of eclipse is a total eclipse. This is where the shadow, or umbra, of the Earth entirely passes over the moon. A partial eclipse occurs when only some of Earth's umbra passes over the moon. A penumbral eclipse occurs when just a little bit of Earth's umbra passes near or over the Moon. A penumbral eclipse may be barely noticeable.
Strictly speaking, people are not in the penumbra or umbra of Earth but may observe these variations of shadows from Earth.
