When the moon passes through the penumbra of the Earth's shadow, it is called a partial lunar eclipse. In this case, only a portion of the moon enters the penumbra, leading to a subtle shading on the moon's surface. If the moon enters the umbra (the darker part of the shadow), that would result in a total lunar eclipse.
