The Moon passed straight through the center of the Earth's shadow at the descending node in Sagittarius of its orbit. Eastern Australia got the best views with mid eclipse occurring at midnight.

The Moon passed through the very center of the Earth's shadow. Totality lasted for 106 minutes, 24 seconds, the longest duration since 13 August 1859 and 3 May 459, and the next longer won't be for at least 1,500 years. This was the last and longest total lunar eclipse of the 20th Century as well as the second longest and last of the second millennium. It was also the seventh longest total lunar eclipse on NASA's Five Millennium catalog of lunar eclipses which covers the years 2000 BCE to 3000 AD. The longest total lunar eclipse ever recorded took place on 31 May 318 and was only 12 seconds longer than this one.

Visibility

It was seen completely over Australia, rising over Asia, and Eastern Africa, and setting over Western North and South America.

Lunar year series

Saros series

Lunar saros series 129, repeating every 18 years and 11 days, containing 71 events, has 11 total lunar eclipses. The first total lunar eclipse of this series was on May 24, 1910, and last will be on September 8, 2090. The two longest occurrence of this series were on July 6, 1982 and July 16, 2000 when totality lasted 106 minutes.

Greatest First

The greatest eclipse of the series occurred on 2000 Jul 16, lasting 106 minutes.		 Penumbral Partial Total Central

It last occurred on July 6, 1982 and will next occur on July 27, 2018.

This is the 37th member of Lunar Saros 129. The previous event was the July 1982 lunar eclipse. The next event is the July 2018 lunar eclipse. Lunar Saros 129 contains 11 total lunar eclipses between 1910 and 2090. Solar Saros 136 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 40.

All events in this series shown (from 1000 to 2500 and beyond) are central total lunar eclipses.

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 136.
