A total lunar eclipse took place on June 15, 2011. It was the first of two such eclipses in 2011. The second occurred on December 10, 2011.

This was a relatively rare central lunar eclipse, in which the center point of Earth's shadow passes across the moon. The last time a lunar eclipse was closer to the center of the earth's shadow was on July 16, 2000. The next central total lunar eclipse was on July 27, 2018 over South America, western Africa, and Europe, and setting over eastern Asia.

Visibility and viewingEdit

 
NASA chart of the eclipse

In western Asia, Australia, and the Philippines, the lunar eclipse was visible just before sunrise.[1] It was very visible in the clear and cloudless night sky throughout eastern and southeast Asia. Africa, far eastern Russia and Europe witnessed the whole event even in the late stages (as in partial lunar eclipse). The Americas (including North and northwestern South America) missed the eclipse completely (except in most areas) because it occurred at moonset.

It was preceded by the partial solar eclipse of January 4, 2011, and the partial solar eclipse of June 1, 2011.

Semester seriesEdit

This eclipse is the center of nine lunar eclipses in a short-lived series. Each eclipse in the series repeats after one semester (6 lunations or 177 days) occurring at alternating nodes.

Saros seriesEdit

Lunar saros series 130, repeating every 18 years and 11 days, has a total of 72 lunar eclipse events including 14 total lunar eclipses.

Greatest First
 
The greatest eclipse of the series will occur on 2029 Jun 26, lasting 102 minutes.[2]

Tritos seriesEdit

The tritos series repeats 31 days short of 11 years at alternating nodes. Sequential events have incremental Saros cycle indices.

This series produces 23 total eclipses between June 22, 1880 and August 9, 2120.

Inex seriesEdit

The inex series repeats eclipses 20 days short of 29 years, repeating on average every 10571.95 days. This period is equal to 358 lunations (synodic months) and 388.5 draconic months. Saros series increment by one on successive Inex events and repeat at alternate ascending and descending lunar nodes.

This period is 383.6734 anomalistic months (the period of the Moon's elliptical orbital precession). Despite the average 0.05 time-of-day shift between subsequent events, the variation of the Moon in its elliptical orbit at each event causes the actual eclipse time to vary significantly.

All events in this series listed below and more are total lunar eclipses.
