The Moon's hourly motion across the Earth's shadow in the constellation of Ophiuchus (north of Scorpius)

A total lunar eclipse took place on 15 June 2011. It was the first of two such eclipses in 2011. The second occurred on 10 December 2011. While the visual effect of a total eclipse is variable, the Moon may have been stained a deep orange or red colour at maximum eclipse.^{[citation needed]}

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 16 July 2000. The next central total lunar eclipse was on 27 July 2018 over South America, western Africa, and Europe, and setting over eastern Asia.^{[citation needed]}

Visibility and viewing

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.

Eclipses of 2011

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

Semester series

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 series

Lunar saros series 130, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 56 umbral lunar eclipses (42 partial lunar eclipses and 14 total lunar eclipses). Solar Saros 137 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Tritos series

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 series

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. It is a part of Lunar Inex series 39.

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