September 1979 Lunar Eclipse
A total lunar eclipse took place on Thursday, September 6, 1979, the second of two lunar eclipses in 1979. A shallow total eclipse saw the Moon in relative darkness for 44 minutes and 24.7 seconds. The Moon was 9.358% of its diameter into the Earth's umbral shadow, and should have been significantly darkened. The partial eclipse lasted for 3 hours, 11 minutes and 54.1 seconds in total. This event followed the annular solar eclipse of August 22, 1979.

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 Eclipse Of August 31, 1970
An annular solar eclipse occurred on Monday, August 31–Tuesday, September 1, 1970. 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 from the Territory of Papua and New Guinea (today's Papua New Guinea), Gilbert and Ellice Islands (the part that belongs to Tuvalu now) on September 1st (Tuesday), West Samoa (name changed to Samoa later) and the whole American Samoa except Swains Island Swains Island (; Tokelauan: ''Olohega'' ; Samoan: ''Olosega'' ) is a remote coral atoll in the Tokelau Islands in the South Pacific Ocean. The island is the subject of an ongoing territorial d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Solar Eclipse Of September 11, 1988
An annular solar eclipse occurred on September 11, 1988. 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.

Solar Saros 144
Saros cycle series 144 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. Saros 144 It is a part of Saros cycle 144, repeating every 18 years, 11 days, containing 70 events. The series started with partial solar eclipse on April 11, 1736. It contains annular eclipses from July 7, 1880 through August 27, 2565. There are no total eclipses in the series. The series ends at member 70 as a partial eclipse on May 5, 2980. The longest duration of annularity will be 9 minutes, 52 seconds on December 29, 2168. 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 144 appears in the following table. Events References * http://eclipse.gsfc.nasa.gov/SEsaros/SEsaros144.ht ...

Solar Eclipse Of August 22, 1979
An annular solar eclipse occurred at the Moon's ascending node of the orbit on Wednesday, August 22, 1979. 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. A small annular eclipse covered only 93% of the Sun in a very broad path, 953 km wide at maximum, and lasted 6 minutes and 3 seconds. This was the second solar eclipse in 1979, the first one a total solar eclipse on February 26. This was the last of 40 umbral eclipses of Solar Saros 125. The first was in 1276 and the last was in 1979. The total duration is 703 years. Related eclipses Eclipses in 1979 * A total solar eclipse on Monday, 26 Februa ...

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.
