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 (Perigee on Wednesday, May 12, 1976), the Moon's apparent diameter 5.4% larger than average. [1]
This is the second eclipse this season.
First eclipse this season: Annular solar eclipse of April 29, 1976

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 total solar eclipse occurred at the Moon’s descending node of the orbit on Thursday, July 11, 1991. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Totality began over the Pacific Ocean and Hawaii moving across Mexico, down through Central America and across South America ending over Brazil. It lasted for 6 minutes and 53.08 seconds at the point of maximum eclipse. There will not be a longer total eclipse until June 13, 2132. This was the largest total solar eclipse of Solar Saros series 136, because eclipse magnitude was 1.07997.
A penumbral lunar eclipse took place at the Moon's ascending node on 11 February 2017, the first of two lunar eclipses in 2017. It was not quite a total penumbral lunar eclipse. It occurred the same day as comet 45P/Honda–Mrkos–Pajdušáková made a close approach to Earth. It also occurred on the Lantern Festival, the first since 9 February 2009. Occurring only 4.4 days after perigee, the moon's apparent diameter was larger.
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 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 occurred on Friday, 5 May 2023, the first of two lunar eclipses in 2023. The moon's apparent diameter was 0.1% larger than average because it occurred 5.5 days before perigee. This was the deepest penumbral eclipse since February 2017 and until September 2042.
A partial lunar eclipse took place on Monday, April 4, 1977, the first of two lunar eclipses in 1977. At maximum eclipse, a small bite out of the Moon should have been visible. The eclipse lasted for 1 hour and 34.76 minutes, with just 19.289% of the Moon in shadow at maximum.
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 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 total lunar eclipse took place on Sunday, January 30, 1972, the first of two lunar eclipses in 1972. The moon entered the Earth's penumbral shadow at 30 January 1972 08:03:12.5 UTC and exited at 30 January 1972 13:43:37.9 UTC. The moon entered the Earth's umbral shadow at 30 January 1972 09:11:38.4 UTC and exited at 30 January 1972 12:35:03.1 UTC. Totality lasted 34 minutes, 47.7 seconds, between 10:35:57.4 UTC and 11:10:45.1 UTC. The moon was 6.6 days before apogee, making it 1.6% smaller than average, only 0.2% larger than the July 1972's lunar eclipse.
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 took place at the Moon's descending node of the orbit on May 9–10 (UTC), 2013, with a magnitude of 0.9544. 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.

An annular solar eclipse occurred at the Moon's descending node of the orbit on February 4–5, 1981. 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. This annular solar eclipse was large because the Moon covered 99.4% of the Sun, with a path width of only 25 km . It was visible in Australia, crossing over Tasmania and southern Stewart Island of New Zealand near sunrise on February 5 (Thursday), and ended at sunset over western South America on February 4 (Wednesday). Occurring only 4 days before perigee, the moon's apparent diameter was larger.
An annular solar eclipse occurred at the Moon's ascending node of the orbit on August 10, 1980, centred over the Pacific Ocean. 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 in Tabuaeran of Kiribati, Peru, Bolivia, northern Paraguay and Brazil. Occurring 5 days before apogee, the Moon's apparent diameter was smaller. At greatest eclipse, the Sun was 79 degrees above horizon.
