A special type of penumbral eclipse is a total penumbral lunar eclipse, during which the entire Moon lies exclusively within Earth's penumbra. Total penumbral eclipses are rare, and when these occur, the portion of the Moon closest to the umbra may appear slightly darker than the rest of the lunar disk.
The penumbral lunar eclipse on March 14, 2006 was a total penumbral eclipse. A total penumbral lunar eclipse is a lunar eclipse that occurs when the Moon becomes completely immersed in the penumbral cone of the Earth without touching the umbra. [1] The path for the Moon to pass within the penumbra and outside the umbra is very narrow. It can ...
For example, NASA's Navigation and Ancillary Information Facility defines that a body in the umbra is also within the penumbra.

What is the penumbra during an eclipse. The second shadow is called the penumbra. ... Lunar eclipses occur at the full moon phase. When Earth is positioned squarely between the moon and sun, Earth ...
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.
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.
A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Monday, March 25, 2024, [1] with an umbral magnitude of −0.1304. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's ...
We are over the moon about this lunation! September's full moon, nicknamed the Harvest Moon, is an exciting one because it doubles as a partial lunar eclipse that peaks on Sept. 17 at 7:44 p.m. PT
