A penumbra refers to a partially shaded outer region of a shadow that an object casts.
A penumbral eclipse occurs when the Moon passes through the faint penumbral portion of the Earth’s shadow.
The lunar surface is not completely shadowed by the Earth’s umbra (darkest part of a shadow).
Instead, observers can see only the slightest dimming near the lunar limb closest to the umbra. The eclipse may be undetectable unless at least half of the Moon enters the penumbra.
