For example, NASA's Navigation and Ancillary Information Facility defines that a body in the umbra is also within the penumbra.

A lunar eclipse is an astronomical event that ... When the Moon's near side penetrates partially into the Earth's umbra, it is known as a partial lunar eclipse, [7] ...
What is an umbra during an eclipse? During an eclipse, two shadows are cast. ... Lunar eclipses occur at the full moon phase. When Earth is positioned squarely between the moon and sun, Earth’s ...
A total lunar eclipse will occur at the Moon’s descending node of orbit on Friday, March 14, 2025, [1] with an umbral magnitude of 1.1804. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow.
During a total lunar eclipse, the moon passes completely through Earth's shadow, which has two parts: the penumbra and umbra, labeled below: lunar eclipse.
A lunar eclipse lasts longer, taking several hours to complete, with totality itself usually averaging anywhere from about 30 minutes to over an hour. [16] There are three types of lunar eclipses: penumbral, when the Moon crosses only the Earth's penumbra; partial, when the Moon crosses partially into the Earth's umbra; and total, when the Moon ...
A lunar eclipse occurs when the Moon passes within Earth's umbra (shadow). As the eclipse begins, the Earth's shadow first darkens the Moon slightly. Then, the shadow begins to "cover" part of the Moon, turning it a dark red-brown color (typically - the color can vary based on atmospheric conditions).
A partial lunar eclipse occurred at the Moon’s ascending node of orbit on Monday, June 15, 1992, [1] with an umbral magnitude of 0.6822. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is ...
