Viewing
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.

Lunar year series

Saros series

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. [1]

Metonic cycle (19 years)

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.

Half-Saros cycle

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 145.
