Asia, Australia, and other areas of the Pacific had the best visibility. European countries only saw a partial eclipse of a rising moon, while northwestern North America saw a partial eclipse of a setting moon.
The eclipse was seen over the Philippines despite cloudy and rainy weather over parts of Luzon and other areas. Photos were taken by groups of amateur astronomers from the Astronomical League of the Philippines (ALP).[citation needed]
South America and portions of West Africa missed the eclipse completely as it happened in the early morning.[citation needed]

Half-Saros cycle
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[1] This lunar eclipse is related to two total solar eclipses of Solar Saros 142.
Lunar year (354 days)
This eclipse is the one of four 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.
