A penumbral lunar eclipse took place at the Moon's descending node of the orbit on Tuesday, August 26, 1980, the last of three penumbral lunar eclipses in 1980 with a penumbral magnitude of 0.70891. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 70.891% 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 3 hours, 34 minutes and 26 seconds.

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 penumbral lunar eclipse took place on Sunday, January 31, 1999, the first of two lunar eclipses in 1999.
A partial lunar eclipse took place on Saturday, June 25, 1983, the first of two lunar eclipses in 1983 with an umbral eclipse magnitude of 0.33479. A partial lunar eclipse happens when the Earth moves between the Sun and the Full Moon, but they are not precisely aligned. Only part of the Moon's visible surface moves into the dark part of the Earth's shadow. A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon is covered by the outer part of the Earth's shadow called the penumbra. The Earth's shadow on the moon was clearly visible in this eclipse, with 33% of the Moon in shadow; the partial eclipse lasted for 2 hours and 15 minutes.
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 Wednesday, October 7, 1987, the second of two lunar eclipses in 1987, the first being on April 14, 1987. The Moon approached within 0.00949% of its diameter outside of touching the Earth’s umbral shadow at maximum eclipse; 98.63% of the Moon's disc was partially shaded by the Earth, with the overall eclipse lasting 4 hours and 14 minutes. While less dramatic than a partial eclipse, a shading across the Moon should have been readily visible to observers. The Moon was just 3.1 days after perigee, making it 2.1% larger than average.
A penumbral lunar eclipse took place on Tuesday, April 14, 1987, the first of two lunar eclipses in 1987, the second being on October 7, 1987. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 77.703% 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 3 hours, 54 minutes and 12.8 seconds. The Moon was just 4.6 days before perigee, making it 0.5% larger than average.
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 penumbral lunar eclipse took place on Tuesday, December 20, 1983, the second of two lunar eclipses in 1983. At the maximum eclipse, 89% of the Moon's disk 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 2 minutes overall.
A penumbral lunar eclipse took place on Tuesday, January 20, 1981, the first of two lunar eclipses in 1981. 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 and 24 minutes in all, though for most of it, the eclipse was extremely difficult or impossible to see. The moon's apparent diameter was larger because the eclipse occurred 5.2 days after perigee.
A penumbral lunar eclipse took place on Sunday, July 27, 1980, the second of three penumbral lunar eclipses in 1980. This very subtle penumbral eclipse was essentially invisible to the naked eye; though it lasted 2 hours, 17 minutes and 36.3 seconds, just 25.354% of the Moon's disc was in partial shadow. The moon passed in the northern edge of the Earth's penumbral shadow, and was the 70th lunar eclipse of Saros cycle 109.
A penumbral lunar eclipse took place on Tuesday, September 27, 1977, the second of two lunar eclipses in 1977. At maximum eclipse, 90.076% 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, 17 minutes and 35.5 seconds overall. Occurring 6.2 days before apogee, the Moon's apparent diameter was 2.2% smaller than average.
A penumbral lunar eclipse took place on Saturday, March 1, 1980, the first of three penumbral lunar eclipses in 1980. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 65.455% 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 3 hours, 58 minutes and 33.3 seconds.
A partial lunar eclipse took place on Thursday, May 13, 1976, the first of two lunar eclipses in 1976, the second being a penumbral lunar eclipse on November 6, 1976. At maximum eclipse, a small bite out of the Moon should have been visible. The eclipse lasted for 1 hour, 15 minutes and 23.8 seconds, with just 12.17% of the Moon in shadow at maximum. Occurring only 1.1 days after perigee, the Moon's apparent diameter 5.4% larger than average.
A penumbral lunar eclipse took place on Saturday, November 6, 1976, the second of two lunar eclipses in 1976, the first being on May 13. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 83.827% 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, 25 minutes and 52.1 seconds. Occurring only 0.3 days after apogee, the moon's apparent diameter was 6.5% smaller than average.
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.

This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 70.337% 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 3 hours, 43 minutes and 46.9 seconds. Occurring only 4.2 days before perigee, the Moon's apparent diameter was 0.9% larger than average.
A penumbral lunar eclipse took place on Thursday, September 25, 1969, the last of three penumbral lunar eclipses in 1969, the first being on Wednesday, April 2, and the second being on Wednesday, August 27. At maximum eclipse, 90% 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 5 minutes overall.
A partial lunar eclipse took place on Saturday, July 6, 1963 with an umbral eclipse magnitude of 0.70602. The Moon was strikingly shadowed in this deep partial eclipse which lasted 3 hours exactly, with 71% of the Moon in darkness at maximum. A partial lunar eclipse occurs when the Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra. The rest of the Moon is covered by the outer part of the Earth's shadow called the penumbra. It was the second of three lunar eclipses in 1963, the first was a penumbral lunar eclipse on January 9, 1963 and the third and last was on December 30, 1963.
A penumbral lunar eclipse took place on Wednesday, December 8, 1965. At maximum eclipse, 88% 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 1 minute overall.
