A partial lunar eclipse occurred on 26 June 2010, the first of two lunar eclipses in 2010. At maximum eclipse, 53.68% of the Moon was covered by the Earth's shadow.[1]
This eclipse is a part of Lunar Saros 120 series, repeating every 18 years and 10 days, last occurring on 15 June 1992, and will next repeat on 6 July 2028. This series is winding down: The final total eclipse of this series was on 14 May 1938 and the final partial lunar eclipse will be on 28 July 2064.
The entire umbral phase was visible after sunset Saturday evening throughout the Pacific, New Zealand, Australia, the Philippines and Japan. The point where the Moon was directly overhead at maximum eclipse lay over the South Pacific Ocean, far to the southwest of Hawaii. The lunar eclipse seen over the Philippines on Saturday evening despite rainshowers and thick clouds, but it was clearly visible throughout the night sky.
It was seen before sunrise on Saturday morning setting over western North and South America:

This eclipse is the one of five lunar eclipses in a short-lived series. The lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two total solar eclipses of Solar Saros 127.
