The Moon passed straight through the center of the Earth's shadow at the descending node in Sagittarius of its orbit.

A total lunar eclipse took place on Sunday 16 July 2000, the second of two total lunar eclipses in 2000.

The Moon passed through the very center of the Earth's shadow. Totality lasted for 106 minutes and 25 seconds, the longest duration since 13 August 1859 (106 minutes and 28 seconds) and 3 May 459 (106 minutes and 32 seconds), and totality of this length won't occur again until 19 August 4753 (106 minutes and 35 seconds). 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 eighth longest total lunar eclipse on EclipseWise's Six Millennium Catalog of Lunar Eclipses which covers the years 3000 BCE to 3000 AD. The longest total lunar eclipse between the years 4000 BCE and 6000 CE took place on 31 May 318. Totality lasted 106 minutes and 36 seconds which is only 11 seconds longer than this one.^[1]

Visibility

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

It last occurred on 27 July 2018, and will next occur on 7 August 2036.

This is the 37th member of Lunar Saros 129. The previous event was the July 2018 lunar eclipse. The next event is the August 2036 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) 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).^[2] This lunar eclipse is related to two total solar eclipses of Solar Saros 136.
