July 1980 Lunar Eclipse
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 (with no part of it in complete shadow). The moon passed in the northern edge of the Earth's penumbral shadow, and was the 70th lunar eclipse of Saros cycle 109. The Moon's apparent diameter was 3.1 days before perigee (Perigee on Wednesday, July 30, 1980), the Moon's apparent diameter was 2.2% larger than average. Visibility It was completely visible over Europe, Africa, the Indian Ocean, Asia and Australia, seen rising over Europe and Africa and setting over Asia and Australia.

Lunar Eclipse
A lunar eclipse occurs when the Moon moves into the Earth's shadow. Such alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, which can happen only on the night of a full moon when the Moon is near either lunar node. The type and length of a lunar eclipse depend on the Moon's proximity to the lunar node. When the moon is totally eclipsed by the Earth, it takes on a reddish color that is caused by the planet when it completely blocks direct sunlight from reaching the Moon surface, as only the light reflected from the lunar surface has been refracted by Earth's atmosphere. This light appears reddish due to the Rayleigh scattering of blue light, the same reason sunrise and sunsets are more orange than during the day. Un ...

Solar Saros 116
Saros cycle series 116 for solar eclipses occurs at the Moon's descending node, repeating every 18 years, 11 days, containing 70 events. All eclipses in this series occurs at the Moon's descending node. This solar saros is linked to Lunar Saros 109. Solar Saros 116 Lunar Saros 109 interleaves with this solar saros with an event occurring every 9 years 5 days alternating between each saros series. Umbral eclipses Umbral eclipses (annular, total and hybrid) can be further classified as either: 1) Central (two limits), 2) Central (one limit) or 3) Non-Central (one limit). The statistical distribution of these classes in Saros series 116 appears in the following table.

Saros (astronomy)
The saros () is a period of exactly 223 synodic months, approximately 6585.3211 days, or 18 years, 10, 11, or 12 days (depending on the number of leap years), and 8 hours, that can be used to predict eclipses of the Sun and Moon. One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. A sar is one half of a saros. A series of eclipses that are separated by one saros is called a ''saros series''. It corresponds to: *6,585.321347 solar days *18.029 years *223 synodic months *241.999 draconic months *18.999 eclipse years (38 eclipse seasons) *238.992 anomalistic months The 19 eclipse years means that if there is a solar eclipse (or lunar eclipse), then after one saros a new moon will take place at the same node of the orbit of the Moon, and under these circumstances another eclipse can occur.

August 1980 Lunar Eclipse
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.
