A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon is covered by the outer part of the Earth's shadow called the penumbra.
Lunar nodes are the locations where the Moon crosses the Earth's orbital plane. Partial lunar eclipses do not happen every Full Moon night because of the inclination of the Moon's orbital plane.

The forthcoming eclipse will also be the longest partial lunar eclipse in years, according to the Holcomb Observatory at Butler University, Indiana. Lunar eclipses happen when Earth slides between the moon and the sun, so that our planet's shadow eclipses or "falls on" the moon. The larger size of the Moon's penumbra compared to its umbra, the shadow's dark center producing total solar eclipses, also means that more places on Earth get to experience a partial solar eclipse.
During a partial solar eclipse, the Moon's umbra or antumbra , the shadow's center portion, is cast into space just above the polar regions, missing Earth by a narrow margin. This means that partial solar eclipses, while potentially being visible at all latitudes , usually center around a place close to one of the poles. When is the next eclipse in your city?

Scientists have debunked these modern superstitions; the only precaution you need to take is protecting your eyes when viewing the Sun.
For the Ancient Greeks, an eclipse was a bad omen, spelling death and destruction caused by an angry god. The Pomo, an indigenous people from the north western United States, tell a story of a bear who started a fight with the Sun and took a bite out of it.
