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. It occurred near perigee, and as described, such event was known as a supermoon.

This small partial eclipse was visible from North America, eastern Asia, Australia, and western South America.

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.

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 partial solar eclipses of Solar Saros 122.

A partial lunar eclipse took place on 16 August 2008, the second of two lunar eclipses in 2008, with the first being a total eclipse on 20 February 2008. The next lunar eclipse was a penumbral eclipse occurring on 9 February 2009, while the next total lunar eclipse occurred on 21 December 2010.
A total lunar eclipse took place on Sunday 9 November 2003, the second of two total lunar eclipses in 2003, the first being on 16 May 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 Sunday 24 April 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 17 October 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 penumbral lunar eclipse took place on 14 March 2006, the first of two lunar eclipses in 2006.
A total lunar eclipse took place on Monday, October 28, 1985, the second of two total lunar eclipses in 1985, the first being on May 4, 1985.
A partial lunar eclipse took place on Saturday, August 27, 1988, the second of two lunar eclipses in 1988, the first being on March 3, 1988. The Earth's shadow on the Moon was clearly visible in this eclipse, with 29.159% of the Moon in shadow; the partial eclipse lasted for 1 hour, 52 minutes and 59.7 seconds. The Moon was only 5 hours and 48 minutes before perigee, making it 6.3% larger than average
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 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, which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 4 hours and 28 minutes.
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 occurred on Saturday, 28 October 2023 (UTC).
A penumbral lunar eclipse took place on 30 November 2020. A penumbral lunar eclipse occurs at full moon when the Moon passes through Earth's penumbral shadow.
A partial lunar eclipse will take place on Friday 28 August 2026. The moon will be almost be inside the umbra, but not quite be contained within the umbral shadow at greatest eclipse.
A penumbral lunar eclipse will take place on 20–21 February 2027.
A penumbral lunar eclipse will take place on Tuesday, August 17, 2027. It will cause a subtle dimming as 54.56% of the Moon will cross within Earth's penumbral 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.
A total lunar eclipse took place on Wednesday, October 18, 1967, the second of two total lunar eclipses in 1967, the first being on April 24, 1967.
A penumbral lunar eclipse will take place on March 3, 2045.
A penumbral lunar eclipse will take place on December 20, 2048.
