Penumbral Lunar Eclipse

About one in three of all lunar eclipses are penumbral. It is impossible to observe the start and end of a penumbral lunar eclipse, even with telescopes. Penumbral eclipses that involve the darker portion of the Earth's penumbral shadow, however, are normally visible to the naked eye.
