A total lunar eclipse took place on Tuesday, 6 July 1982, the second of three total lunar eclipses in 1982, and the only one that was in the descending node. A dramatic total eclipse lasting 1 hour and 46 minutes plunged the full Moon into deep darkness, as it passed right through the centre of the Earth's umbral shadow. 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. This was a great spectacle for everyone who saw it. The partial eclipse lasted for 3 hours and 56 minutes in total.

The moon passed through the center of the Earth's shadow.^{[citation needed]}

Visibility

It was seen completely over North and South America, seen rising over Australia, and setting over Western Africa.^{[citation needed]}

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 longest occurrence of this series was on July 16, 2000 when totality lasted 106 minutes and 24.6 seconds.

It last occurred on 25 June 1964 and will next occur on 16 July 2000.

This is the 36th member of Lunar Saros 129. The previous event was the June 1964 lunar eclipse. The next event is the July 2000 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.^{[citation needed]}

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.

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.

June 30, 1973	July 11, 1991
