November 1976 Lunar Eclipse
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 (none of it was in total shadow), 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 (Apogee on Saturday, November 6, 1976), the Moon's apparent diameter was 6.5% smaller than average. Saros series This is the 9th member of Lunar Saros 145. The previous event was the October 1958 lunar eclipse. The next event is the November 1994 lunar eclipse. Solar Saros 152 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

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. ...

Solar Eclipse Of November 12, 1985
A total solar eclipse occurred on November 12, 1985. 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. It was visible only near Antarctica Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean, it contains the geographic South Pole. Antarctica is the fifth-largest co ....

December 1983 Lunar Eclipse
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.

September 1969 Lunar Eclipse
A penumbral lunar eclipse took place on Thursday, September 25, 1969, the last of three penumbral lunar eclipses in 1969, the first being on Wednesday, April 2, and the second being on Wednesday, August 27. At maximum eclipse, 90% 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 and 5 minutes overall. Visibility It was completely visible over Europe, Africa, Asia and Australia.

Solar Eclipse Of November 2, 1967
A total solar eclipse occurred on November 2, 1967. 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 The angular diameter, angular size, apparent diameter, or apparent size is an angular distance describing how large a sphere or circle appears from a given point of view. In the vision sciences, it is called the visual angle, and in optics, it is ... 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. This ''total'' eclipse was very unusual in that it was ''NON-CENTRAL'' and did ''NOT'' have a ''central line'' nor a southern path limit. Instead, over half of the umbral shadow fell off into space throughout the eclipse. ''Gamma'' had a val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
May 1976 Lunar Eclipse
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. Eclipse season This is the second eclipse this season.

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.
