A lunar eclipse occurs whenever the Moon passes through some portion of the Earth's shadow. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, the Moon is always full during a lunar eclipse. The type and length of an eclipse depend upon the Moon's location relative to its orbital nodes. The most recent total lunar eclipse was on 28 August 2007[1] where the sun, earth and moon were in total alignment; see 28 August 2007 lunar eclipse. The initial stage started at 07:52 UTC, while the total eclipse began at 09:52 UTC turning it bronze, with reddish to blood red at its peak. Sydney and New Zealand were in the perfect zone to view the 1st total lunar rare eclipse or "blood moon" since July 2000.[2]

月蝕分幾個階段：（以下摘自維基百科）
- 半影食始：月球剛剛和半影區接觸，這時月球表面光度略為減少，但肉眼較難覺察。
- 初虧：月球由東緣慢慢進入地影，月球與地球本影第一次外切。
- 食既：月球進入地球本影，並與本影第一次內切。
- 食甚：月圓面中心與地球本影中心最接近的瞬間，此時前後月球表面呈紅銅色或暗紅色。
- 生光：月球在地球本影內移動，並與地球本影第二次內切。
- 復圓：月球逐漸離開地球本影，與地球本影第二次外切。
- 半影食終：月球離開半影，整個月食過程正式完結。
