A partial lunar eclipse took place on Monday, December 10, 1973, the last of four lunar eclipses in 1973. At maximum eclipse, a small bite out of the Moon should have been visible. The eclipse lasted for 1 hour, 8 minutes and 29.4 seconds, with just 10.069% of the Moon in shadow at maximum. [1] It occurred near perigee, and as described, such event was known as a supermoon.

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 Sunday 30 December 2001, the last of three lunar eclipses in 2001. At maximum eclipse, 89.477% 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, 4 minutes and 17.7 seconds overall. This lunar eclipse followed the Annular Solar Eclipse on 14 December 2001.
A partial lunar eclipse took place on Thursday 5 July 2001, the second of three lunar eclipses in 2001. The Earth's shadow on the moon was clearly visible in this eclipse, with 49.614% of the Moon in shadow; the partial eclipse lasted for 2 hours, 40 minutes and 0.5 seconds. Occurring only 3.9 days before apogee, the Moon’s apparent diameter was 5.021% smaller than average.
A total lunar eclipse took place at the Moon's descending node of the orbit on Tuesday, September 16, 1997, the second of two lunar eclipses in 1997. A shallow total eclipse saw the Moon in relative darkness for 1 hour, 1 minute and 30.8 seconds. The Moon was 19.094% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 16 minutes and 28.2 seconds in total. The penumbral eclipse lasted for 5 hours, 8 minutes and 20.1 seconds. The partial eclipse lasted for 3 hours, 16 minutes and 28.2 seconds. The total eclipse lasted for 1 hour, 1 minute and 30.8 seconds. Maximum eclipse was at 18:46:39.1 UTC. The moon's apparent diameter was extremely large because occurred only 3 hours and 21 minutes past perigee. The Moon was only 356,986 km of the Earth at greatest eclipse.
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, 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, if not impossible to see. The moon's apparent diameter was larger because the eclipse occurred 5.2 days after perigee.
A total lunar eclipse took place on Friday, November 29, 1974, the second of two lunar eclipses in 1974. The Moon was plunged into darkness for 1 hour, 15 minutes and 45 seconds, in a deep total eclipse which saw the Moon 28.961% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours, 28 minutes and 58.7 seconds in total. The penumbral eclipse lasted for 5 hours, 33 minutes and 11.6 seconds. The partial eclipse lasted for 3 hours, 28 minutes and 58.7 seconds. The total eclipse lasted for 1 hour, 15 minutes and 45 seconds. Occurring only 3.6 days before perigee, the Moon's apparent diameter was 1.4% larger than average.
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 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, 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 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 Friday, June 15, 1973, the second of four lunar eclipses in 1973, the first was a penumbral lunar eclipse on Thursday, January 18, the third being with a penumbral lunar eclipse on Sunday, July 15, and the last being with a partial lunar eclipse on Monday, December 10.
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 penumbral lunar eclipse took place on Thursday, January 18, 1973, the first of four lunar eclipses in 1973, the second being with a penumbral lunar eclipse on Friday, June 15, the third being with a penumbral lunar eclipse on Sunday, July 15, and the last being with a partial lunar eclipse on Monday, December 10.
A penumbral lunar eclipse took place on Sunday, July 15, 1973, the third of four lunar eclipses in 1973, the first was a penumbral lunar eclipse on Thursday, January 18, the second was a penumbral lunar eclipse on Friday, June 15, and the last being with a partial lunar eclipse on Monday, December 10.
A penumbral lunar eclipse took place on Wednesday, April 2, 1969, the first of three penumbral lunar eclipses in 1969, the second being on Wednesday, August 27, and the last being on Thursday, September 25. 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.
An annular solar eclipse occurred on December 24, 1973. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible from southern Mexico, southwestern Nicaragua, Costa Rica including the capital city San José, Panama, Colombia including the capital city Bogotá, southern Venezuela, Brazil, southern Guyana, southern Dutch Guiana, southern French Guiana, Portuguese Cape Verde including the capital city Praia, Mauritania including the capital city Nouakchott, Spanish Sahara, Mali, and Algeria.
