Solar Saros 115
Saros cycle series 115 for solar eclipses occurs at the Moon's ascending node, repeating every 18 years, 11 days, containing 72 events. All eclipses in this series occurs at the Moon's ascending node. This solar saros is linked to Lunar Saros 108. 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 115 appears in the following table.

Saros Cycle
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
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of the Earth, totally or partially. Such an alignment occurs during an eclipse season, approximately every six months, during the new moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years. If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. Instead, because the ...

Gamma (solar Eclipse)
Gamma (denoted as γ) of an eclipse describes how centrally the shadow of the Moon or Earth strikes the other body. This distance, measured at the moment when the axis of the shadow cone passes closest to the center of the Earth or Moon, is stated as a fraction of the equatorial radius of the Earth or Moon. Sign The sign of gamma defines, for a solar eclipse, if the axis of the shadow passes north or south of the center of the Earth; a positive value means north. The Earth is defined as that half which is exposed to the Sun (this changes with the seasons and is not related directly to the Earth's poles or equator; thus, the Earth's center is wherever the Sun is directly overhead). For a lunar eclipse, it defines whether the axis of the Earth's shadow passes north or south of the Moon; a positive value means south. Gamma changes monotonically throughout any single saros series. The change in gamma is larger when Earth is near its aphelion (June to July) than when it is near p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Magnitude Of Eclipse
The magnitude of eclipse is the fraction of the angular diameter of a celestial body being eclipsed. This applies to all celestial eclipses. The magnitude of a partial or annular solar eclipse is always between 0.0 and 1.0, while the magnitude of a total solar eclipse is always greater than or equal to 1.0. This measure is strictly a ratio of diameters and should not be confused with the covered fraction of the apparent area (disk) of the eclipsed body. Neither should it be confused with the astronomical magnitude scale of apparent brightness. Effect of the magnitude on a solar eclipse The apparent sizes of the Moon and Sun are both approximately 0.5°, or 30', but both vary because the distance between Earth and Moon varies. (The distance between Earth and Sun also varies, but the effect is slight in comparison.) In an annular solar eclipse, the magnitude of the eclipse is the ratio between the apparent angular diameters of the Moon and that of the Sun during the maxi ...

Solar Eclipse Of May 1, 1185
The solar eclipse of 1 May 1185 was a total solar eclipse visible in Central America, Northern Europe, Eastern Europe, and Kazakhstan. The eclipse is number 30 in the Solar Saros 115 series. The eclipse shadow on the Earth's surface was at its greatest at 13:18:02 Universal Time. The sun was in Taurus at this time. Eclipse path The shadow axis passed between the Earth's center and the north pole. The minimum distance from the center of the Earth to the Moon's shadow cone axis was 3,357 kilometers. The average length of the Moon's shadow was 373,320 kilometers. The distance from the Earth to the Moon on 1 May 1185 was 347,727 kilometers. The apparent diameter of the Moon was 1.0736 times that of the sun. The shadow had a maximum width of 280 kilometers. It began on the west coast of Central America and crossed the Atlantic Ocean in a northeasterly direction. The shadow passed through present-day Nicaragua and Haiti. The maximum duration of the eclipse occurred in the middle of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of July 21, 1906
A partial solar eclipse occurred on July 21, 1906. A solar eclipse occurs when the Moon passes between Earth and the Sun The Sun is the star at the center of the Solar System. It is a nearly perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions in its core. The Sun radiates this energy mainly as light, ultraviolet, and infrared rad ..., thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

Solar Eclipse Of July 31, 1924
This is a list of solar eclipses in the 20th century. During the period 1901 to 2000 there were 228 solar eclipses of which 78 were partial, 73 were annular (two Solar eclipse#Terminology for central eclipse, non-central), 71 were total (three non-central) and 6 were hybrids. The greatest number of eclipses in one year was five, in 1935, and one month, July 2000, had two eclipses. Notable eclipses of the 20th century * Solar eclipse of May 29, 1919, 29 May 1919: this total eclipse was photographed by Arthur Eddington to verify general relativity (see Eddington experiment) * Solar eclipse of June 20, 1955, 20 June 1955: longest total eclipse between 1901 and 2000, lasting a maximum of 7 minutes and 8 seconds * Solar eclipse of June 30, 1973, 30 June 1973: a Concorde jet flew along the path, thereby extending the length of totality to 74 min. * Solar eclipse of March 29, 1987, 29 March 1987: second hybrid eclipse in less than one year, the first being on Solar eclipse of October 3, ...

Solar Eclipse Of August 12, 1942
A partial solar eclipse occurred at the Moon's ascending node of orbit on Wednesday, August 12, 1942, with a magnitude of 0.0561. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth. A partial eclipse was visible for parts of Antarctica. This was the last of 72 solar eclipses in Solar Saros 115. Eclipse details Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse. Eclipse season This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and ...
