A partial lunar eclipse took place on 16 August 2008, the second of two lunar eclipses in 2008, with the first being a total eclipse on 20 February 2008. The next lunar eclipse was a penumbral eclipse occurring on 9 February 2009, while the next total lunar eclipse occurred on 21 December 2010.

The Moon's apparent diameter was 26.2 arcseconds smaller than the 21 February 2008 total lunar eclipse.

NASA chart of the eclipse
 
These simulated views of the Earth from the center of the Moon during the lunar eclipse show where the eclipse is visible on Earth.

Parts of Australia saw it begin before sunrise, while parts of South America saw it end just after sunset. The eclipse is also seen in the Philippines and other parts of Asia at moonset. Parts of Europe, the Middle East and Africa saw it when it is visible.

The penumbral eclipse began at 18:23 UTC, with the partial eclipse beginning at 19:36. The time of greatest eclipse was 21:10. The partial eclipse ended at 22:44, and the penumbral eclipse will ended at 23:57.

The planet Neptune was 2 days past opposition, visible in binoculars as an 8th magnitude "star" just two degrees west and slightly south of the Moon.

Saros series

edit

Lunar saros series 138 has 26 total eclipses between September 7, 2044 and March 24, 2369. The longest eclipse will be on January 7, 2243, and last for 102 minutes.

Partial eclipses will occur between June 24, 1918 and August 13, 2603. Penumbral eclipses will occur between October 15, 1521 and March 30, 2982. [2]

Metonic cycle (19 years)

edit

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will in nearly the same location relative to the background stars.
