A total lunar eclipse took place on Friday 16 May 2003, the first of two total lunar eclipses in 2003, the other being on 9 November 2003. A shallow total eclipse saw the Moon in relative darkness for 52 minutes and 3.1 seconds. The Moon was 12.938% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 15 minutes and 3.1 seconds in total. Occurring only 0.5 days after perigee, the Moon's apparent diameter was 6.2% larger than average. At greatest eclipse the Moon was only 357,693 km from the Earth, making it a Super Full Moon.
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 lunar eclipse will take place between Monday and Tuesday, June 25-26, 2029. A central total eclipse lasting 1 hour and 41 minutes 53 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 color at maximum eclipse. It will be able to be seen from most of the Americas, Western Europe and Africa. The partial eclipse will last for 3 hours and 39 minutes 32 seconds in total.
A total lunar eclipse took place on Friday, March 24, 1978, the first of two total lunar eclipses in 1978. The moon passed through the center of the Earth's shadow. The Moon was plunged into darkness for 1 hour, 30 minutes and 40.2 seconds, in a deep total eclipse which saw the Moon 45.179% 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, 38 minutes and 34.5 seconds in total.
A total lunar eclipse took place on Saturday, May 24 and Sunday, May 25, 1975, the first of two total lunar eclipses in 1975. The Moon was plunged into darkness for 1 hour and 28 minutes in a deep total eclipse which saw the Moon 43% of its diameter inside the Earth's umbral shadow. The visual effect of an eclipse 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 and 35 minutes in total. Occurring only 4.4 days after perigee, the Moon's apparent diameter was 0.7% larger than average. The moon was 377,010 km from the Earth at greatest eclipse.
A total lunar eclipse took place on Saturday, January 9 and Sunday, January 10, 1982, the first of three lunar eclipses in 1982. The Moon was plunged into darkness for 1 hour and 17 minutes 39.5 seconds, in a deep total eclipse which saw the Moon 33.103% 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 and 24 minutes in total.
A total lunar eclipse took place on Thursday, April 24, 1986, the first of two total lunar eclipses in 1986, the second being on October 17, 1986. The Moon was plunged into darkness for 1 hour, 3 minutes and 34.8 seconds, in a deep total eclipse which saw the Moon 20.217% 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, 18 minutes and 46.8 seconds in total. The Moon was just 1.2 days before perigee, making it 5.3% larger than average.
A total lunar eclipse took place on Friday, October 17, 1986, the second of two total lunar eclipses in 1986, the first being on April 24, 1986. The Moon was plunged into darkness for 1 hour, 13 minutes and 41 seconds, in a deep total eclipse which saw the Moon 24.545% 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, 36 minutes and 49.5 seconds in total. The Moon was 5.4 days before apogee, making it 3.3% smaller than average.
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.
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 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 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 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 partial lunar eclipse took place on Monday, August 17, 1970, the second of two lunar eclipses in 1970, the first was on February 21 of that year. The Earth's shadow on the Moon was clearly visible in this eclipse, with 41% of the Moon in shadow; the partial eclipse lasted for 2 hours and 11 minutes. It was the second of two lunar eclipses in 1970.
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.
A partial lunar eclipse took place on Tuesday, August 5, 1952. The Earth's shadow on the Moon was clearly visible in this eclipse, with 53.2% of the Moon in shadow; the partial eclipse lasted for 2 hours and 27 minutes. The Moon's apparent diameter was larger and Supermoon because the eclipse occurred only 45 minutes before perigee.
An annular solar eclipse took place on February 26, 2017. 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. Occurring only 4.7 days before perigee, the Moon's apparent diameter was larger. The moon's apparent diameter was just over 0.7% smaller than the Sun's.
A total solar eclipse occurred on July 20, 1963. 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 at least the same size as the Sun's or larger, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with a partial solar eclipse visible over the surrounding region thousands of kilometres wide. Totality was visible from Hokkaido in Japan and Kuril Islands in Soviet Union on July 21, and Alaska, and Maine in the United States and also Canada on July 20. Astronomer Charles H. Smiley observed the eclipse from a U.S. Air Force F-104D Starfighter supersonic aircraft that was "racing the moon's shadow" at 1,300 mph (2,100 km/h) extending the duration of totality to 4 minutes 3 seconds. The moon was 375,819 km from the Earth.
