September 1977 Lunar Eclipse
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 (Apogee on October 3, 1977), the Moon's apparent diameter was 2.2% smaller than average. Visibility It was completely visible over east in Asia, Australia, Pacific, North America and South America, seen rising over Asia, East China Sea and Australia and setting over the Atlantic and South America.

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 ...

April 1977 Lunar Eclipse
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. Visibilility It was completely visible over North America, South America, Europe and Asia, seen rising over the Pacific and setting over the Middle East.

Solar Eclipse Of April 18, 1977
An annular solar eclipse took place at the Moon's descending node of the orbit on Monday, April 18, 1977. 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 South West Africa (today's Namibia), Angola, Zambia, southeastern Zaire (today's Democratic Republic of Congo), northern Malawi, Tanzania, Seychelles Seychelles (, ; ), officially the Republic of Seychelles (french: link=no, République des Seychelles; Creole: ''La Repiblik Sesel''), is an archipelagic state consisting of 115 islands in the Indian Ocean.

Solar Eclipse Of October 12, 1977
A total solar eclipse occurred at the Moon's ascending node of the orbit on Wednesday, October 12, 1977. 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 was visible in the Pacific Ocean, Colombia and Venezuela Venezuela (; ), officially the Bolivarian Republic of Venezuela ( es, link=no, República Bolivariana de Venezuela), is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in th ....

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.

Solar Eclipse Of September 22, 1968
A total solar eclipse occurred on September 22, 1968. 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 was visible from the Soviet Union (today's Russia and Kazakhstan) and Xinjiang in Northwestern China. Observation Soviet Union A company named Opton proposed to the Sternberg Astronomical Institute to observe this solar eclipse in Sary Shagan on the west bank of Lake Balkhash, and also wrote to the Soviet Ministry of Railways for help to get to the destination faster. The observation team obtained spectrum of the corona. Students also assisted in taking pictures of the coro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of October 3, 1986
A hybrid solar eclipse occurred on October 3, 1986. A hybrid eclipse starts and ends as an annular, but is total in the middle around the point of greatest eclipse. Totality occurred for a very short time (calculated at 0.08 seconds) in an area in the Atlantic Ocean, just east of the southern tip of Greenland. The path, on the surface of the Earth, was a narrow, tapered, horse-shoe, and visible only from a thin strip between Iceland and Greenland. At maximum eclipse the solar elevation was about 6°. The path width was just about 800 meters wide. This eclipse was the last central eclipse of Solar Saros 124, saros 124 and the only hybrid eclipse of that saros. Solar Saros 124 This is the eclipse number 53 of Solar Saros 124. Saros cycle 124, repeating every 18 years, 11 days, containing 73 events. The series started with partial solar eclipse on March 6, 1049. It contains total eclipses from June 12, 1211 through September 22, 1968 with one hybrid solar eclipse on October 3, 1 ...
