PICTURES: Nairobi among cities that experienced Supermoon, next appearance in 2033

Sky-watchers around the world were treated when the shadow of Earth cast a reddish glow on the moon, the result of rare combination of an eclipse with the closest full moon of the year. The total "supermoon" lunar eclipse, also known as a "blood moon" is one that appears bigger and brighter than usual as it reaches the point in its orbit that is closest to Earth.

A supermoon occurs when the Moon is in the closest part of its orbit to Earth, meaning it appears larger in the sky. This phenomenon was last observed in 1982 and won't come again until 2033.
