    en.wikipedia.org/wiki/Umbra,_penumbra_and_antumbra

    An observer in the penumbra experiences a partial eclipse. An alternative definition is that the penumbra is the region where some or all of the light source is obscured (i.e., the umbra is a subset of the penumbra). For example, NASA's Navigation and Ancillary Information Facility defines that a body in the umbra is also within the penumbra. [2]

    The penumbral lunar eclipse on March 14, 2006 was a total penumbral eclipse.

  8. Magnitude of eclipse - Wikipedia

    en.wikipedia.org/wiki/Magnitude_of_eclipse

    A lunar eclipse will have two geometric magnitudes: the umbral magnitude and the penumbral magnitude. If the three bodies are not aligned enough, the Moon does not reach into the Earth's umbra - it may still pass through the Earth's penumbra though, and such an eclipse is called a penumbral eclipse.

  9. Eclipse - Wikipedia

    en.wikipedia.org/wiki/Eclipse

    A total eclipse occurs when the observer is within the umbra, an annular eclipse when the observer is within the antumbra, and a partial eclipse when the observer is within the penumbra. During a lunar eclipse only the umbra and penumbra are applicable, because the antumbra of the Sun-Earth system lies far beyond the Moon.
