A penumbral lunar eclipse took place on Thursday, November 8, 1984, the last of three lunar eclipses in 1984. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 90% of the Moon's disc was partially shaded by the Earth (none of it was in total shadow), which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 4 hours and 28 minutes.

Metonic series

This eclipse is the first of five Metonic cycle lunar eclipses on the same date, November 8–9, each separated by 19 years:

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will be in nearly the same location relative to the background stars.

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 partial solar eclipses of Solar Saros 123.

A total lunar eclipse took place on Sunday, November 9, 2003, the second of two total lunar eclipses in 2003, the first being on May 16, 2003. It is the first total lunar eclipse of 21st century which happened on a micromoon day. The Moon barely edged into total eclipse for 21 minutes and 58 seconds. With the Moon just 1.78% of its diameter into the Earth's umbral shadow, the Moon may have been quite bright, but even so, this should have been worth seeing. The partial eclipse lasted for 3 hours, 31 minutes and 25 seconds. Occurring only 1.4 days before apogee, the Moon's apparent diameter was 6.4% smaller than average.

A penumbral lunar eclipse took place on April 24, 2005, the first of two lunar eclipses in 2005. At maximum eclipse, 86.5% of the Moon's disc was partially shaded by the Earth, which caused a slight shadow gradient across its disc; this subtle effect may have been visible to careful observers. No part of the Moon was in complete shadow. The eclipse lasted 4 hours and 6 minutes overall, and was visible from east Asia, Australia, and the Americas.

A partial lunar eclipse took place on Monday, October 17, 2005, the second of two lunar eclipses in 2005. A tiny bite out of the Moon may have been visible at maximum, though just 6.25% of the Moon was shadowed in a partial eclipse which lasted for nearly 56 minutes and was visible over east Asia, Australasia, and most of the North America. A shading across the moon from the Earth's penumbral shadow should have been visible at maximum eclipse.

A total lunar eclipse occurred on Tuesday, 8 November 2022. The southern limb of the Moon passed through the center of the Earth's shadow. It surpassed the previous eclipse as the longest total lunar eclipse visible from nearly all of North America since 17 August 1989, and until 26 June 2029. Occurring only 5.8 days before apogee, the Moon's apparent diameter was smaller. The next total lunar eclipse will take place on 14 March 2025. A lunar occultation of Uranus happened during the eclipse. It was the first total lunar eclipse on Election Day in US history. This event was referred in media coverage as a "beaver blood moon".

A partial lunar eclipse took place on Saturday, December 21, 1991, the last of four lunar eclipses in 1991. The moon grazed the northern edge of the umbral shadow.

A penumbral lunar eclipse took place on Thursday, March 3, 1988, the first of two lunar eclipses in 1988, the second being on August 27, 1988. Earlier sources compute this as a 0.3% partial eclipse lasting under 14 minutes, and newest calculations list it as a penumbral eclipse that never enters the umbral shadow. In a rare total penumbral eclipse, the entire Moon was partially shaded by the Earth, and the shading across the Moon should have been quite visible at maximum eclipse. The penumbral phase lasted for 4 hours, 53 minutes and 50.6 seconds in all, though for most of it, the eclipse was extremely difficult or impossible to see. The Moon was 2.2 days after apogee, making it 6.1% smaller than average.

A penumbral lunar eclipse took place on Thursday, June 27, 1991, the second of four lunar eclipses in 1991. The moon entered the Earth's penumbra for about 3 hours, and was difficult to see. This lunar eclipse is the predecessor of the Solar eclipse of July 11, 1991.

A penumbral lunar eclipse took place on Tuesday, May 15, 1984, the first of three lunar eclipses in 1984. This was a deep penumbral eclipse, with the southern limb of the Moon close to the Earth's shadow.

A partial lunar eclipse took place on Saturday, February 21, 1970. It was the first of two partial lunar eclipses in 1970, the other being on August 17 of the same year. A tiny bite out of the Moon may have been visible at maximum, though just 5% of the Moon was shadowed in a partial eclipse which lasted for 52 minutes and 42 seconds. A shading across the moon from the Earth's penumbral shadow should have been visible at maximum eclipse.

<span class="mw-page-title-main">June 2123 lunar eclipse</span> Spectacular long central lunar eclipse

A total lunar eclipse will occur on Wednesday, June 9, 2123, with maximum eclipse at 05:06 UTC. A dramatic total eclipse lasting 106 minutes and 6 seconds will plunge the full Moon into deep darkness, as it passes right through the centre of the Earth's umbral shadow. While the visual effect of a total eclipse is variable, the Moon may be stained a deep orange or red colour at maximum eclipse. This will be a great spectacle for everyone who sees it. The partial eclipse will last for 3 hours and 56 minutes in total. The penumbral eclipse lasts for 6 hours and 14 minutes. Maximum eclipse is at 05:06:28 UT. This will be the longest Total Lunar Eclipse since 16 July 2000, and the longest one until 12 May 2264 and 27 July 3107, though the eclipse on June 19, 2141 will be nearly identical in all aspects. This will also be the longest of the 22nd century and the second longest of the 3rd millennium. The eclipse on June 19, 2141 will be the second longest of the 22nd century and the third longest of the third millennium.
