A total lunar eclipse took place at the Moon's descending node of the orbit on Wednesday, February 10, 1971, the first of two total lunar eclipses in 1971. It had an umbral magnitude of 1.30819. The Moon passed through the center of the Earth's shadow. The Moon was plunged into darkness for 1 hour, 22 minutes and 11.4 seconds, in a deep total eclipse which saw the Moon 30.819% 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, 44 minutes and 42.9 seconds and in total. Occurring only 2.7 days before apogee (Apogee on Saturday, February 13, 1971), the Moon's apparent diameter was 5.9% smaller than average.

Saros series

Lunar saros series 123, repeating every 18 years and 11 days, has 25 total lunar eclipses. The first total lunar eclipse of this series was on July 16, 1628 , and last will be on April 4, 2061 . The two longest occurrence of this series were on September 20, 1736 and October 1, 1754 when totality lasted 106 minutes.

It last occurred on January 29, 1953 and will next occur on February 20, 1989.

Half-Saros cycle

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 total solar eclipses of Solar Saros 130.

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 Tuesday, January 20, 1981, the first of two lunar eclipses in 1981.

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 total lunar eclipse took place on Saturday, September 16, 1978, the second of two total lunar eclipses in 1978.

A total lunar eclipse took place on Tuesday, November 18, 1975, the second of two total lunar eclipses in 1975. A shallow total eclipse saw the Moon in relative darkness for 40 minutes and 11.1 seconds. The Moon was 6.421% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 29 minutes and 2.1 seconds in total.

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 total lunar eclipse took place at the Moon's descending node of the orbit on Tuesday, May 24, 1910 with an umbral eclipse magnitude of 1.09503. A total lunar eclipse takes place when the Earth comes between the Sun and the Moon and its shadow covers the Moon. Eclipse watchers can see the Moon turn red when the eclipse reaches totality. Total eclipses of the Moon happen at Full Moon when the Sun, Earth, and Moon are aligned to form a line. The astronomical term for this type of alignment is syzygy, which comes from the Greek word for being paired together. The Moon does not have its own light but shines because its surface reflects the Sun's rays. During a total lunar eclipse, the Earth comes between the Sun and the Moon and blocks any direct sunlight from reaching the Moon. The Sun casts the Earth's shadow on the Moon's surface. A shallow total eclipse saw the Moon in relative darkness for 49 minutes and 29.5 seconds. The Moon was 9.503% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 35 minutes and 22.9 seconds in total.
