What is the Saros used for?

Thus, the Saros is useful for organizing eclipses into families or series. Each series typically lasts 12 to 13 centuries and contains 70 or more eclipses. Every saros series begins with a number of partial eclipses near one of Earths polar regions.

What is the saros period?

The Saros arises from a natural harmony between three of the Moons orbital periods (circa 2000 CE): One Saros is equal to 223 synodic months. However, 239 anomalistic months and 242 draconic months are also equal to this same period (to within a couple hours)!

What is the saros series for a solar eclipse?

A typical Saros series for a solar eclipse begins when new Moon occurs ~18° east of a node. If the first eclipse occurs at the Moons descending node, the Moons umbral shadow will pass ~3500 km below Earth and a partial eclipse will be visible from the south polar region.

What is saros series 120?

Solar eclipses of Saros 120 all occur at the Moon’s descending node and the Moon moves northward with each eclipse. The series began with a partial eclipse in the southern hemisphere on 0933 May 27. The series will end with a partial eclipse in the northern hemisphere on 2195 Jul 07. The total duration of Saros series 120 is 1262.11 years.

What is a Saros?

Jump to navigation Jump to search. The saros (/ˈsɛərɒs/ (listen)) is a period of exactly 223 synodic months (approximately 6585.3211 days, or 18 years, 11 days, 8 hours), that can be used to predict eclipses of the Sun and Moon.

What happens during a saros period?

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.

What is the saros series for a solar eclipse?

A typical Saros series for a solar eclipse begins when new Moon occurs ~18° east of a node. If the first eclipse occurs at the Moons descending node, the Moons umbral shadow will pass ~3500 km below Earth and a partial eclipse will be visible from the south polar region.

What is the numbering system used for the saros series?

The numbering system used for the Saros series was introduced by the Dutch Astronomer G. van den Bergh in his book Periodicity and Variation of Solar (and Lunar) Eclipses (Tjeenk Willink, Haarlem, Netherlands, 1955). He placed all 8,000 solar eclipses in von Oppolzers Canon der Finsternisse (1887) into a large two-dimensional matrix.

What is a Saros series?

A series of eclipses that are separated by one saros is called a saros series. It corresponds to: 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.

How do you determine if an eclipse is a Saros series?

If there is an eclipse one inex (29 years minus about 20 days) after an eclipse of a particular saros series then it is a member of the next series. For example, the eclipse of October 26, 1961 BC is in solar saros series 2.

What is the Solar Saros cycle?

Saros Cycle - A measurement of time. Of the 72 eclipses in the series, 44 will be total eclipses. The approximate length of time between each occurrence will be 18 years, 11 days and 8 hours. Solar Saros 136 belongs to Node Family 11 and originated from the calculations of the Moons South Node.

How many solar eclipses will occur in Solar Saros series 136?

Solar Saros Series 136 will exhibit 72 solar eclipses. Of the 72 eclipses in the series, 44 will be total eclipses. The approximate length of time between each occurrence will be 18 years, 11 days and 8 hours. Solar Saros 136 belongs to Node Family 11 and originated from the calculations of the Moons South Node.
