  Eclipse cycle - Wikipedia, the free encyclopedia
Eclipses may occur when the Earth and Moon are on one line with the Sun, and the shadow of one body cast by the Sun falls on the other.
This is nearly equal to 19 tropical years, but is also 5 "octon" periods and close to 20 eclipse years: so it yields a short series of eclipses on the same calendar date.

A tropical year is the time for the Earth to complete one revolution with respect to the framework provided by the intersection of the ecliptic (the plane of the orbit of the Earth) and the plane of the equator (the plane perpendicular to the rotation axis of the Earth).
The eclipse year or ecliptic year is the time for the Sun (as seen from the Earth) to complete one revolution with respect to a node of the Moon's orbit (the points where the Moon's orbit intersects the ecliptic).
A heliacal year or sidereal year is the interval between the heliacal risings of a star.

 Year - Wikipedia, the free encyclopedia
A seasonal year is the time between successive recurrences of a seasonal event such as the flooding of a river, the migration of a species of bird, the flowering of a species of plant, the first frost, or the first scheduled game of a certain sport.
The draconitic year, eclipse year or ecliptic year is the time for the Sun (as seen from the Earth) to complete one revolution with respect to the same lunar node (a point where the Moon's orbit intersects the ecliptic).
The Gaussian year is the sidereal year for a planet of negligible mass (relative to the Sun) and unperturbed by other planets that is governed by the Gaussian gravitational constant.

 Laser Beamed Power   (Site not responding. Last check: 2007-10-29)
Eclipse duration is maximum at the equinox, when it reaches 69 minutes, about 5 percent of the orbit [3].
Since the eclipse power requirement is for 90 periods per year of roughly one hour, 99.9% beam availability corresponds to a 9% chance of losing illumination per year, or a 11 year mean time between loss of illumination.
Since the average eclipse duration is less than this, in general a single loss of illumination will not be a contractrual lapse if the satellite can be re-acquired quickly after eclipse and other failures do not occur.

Partial phases of the eclipse are visible from much of Europe (except Spain and Portugal) and the Middle East where the event occurs at sunrise, as well as from central and northern Asia (excluding most of China, South East Asia and Japan).
Eclipse obscuration is defined as the fraction of the Sun's surface area occulted by the Moon.
For lunar eclipses, the diameter of the umbral shadow was enlarged by 2% to compensate for Earth's atmosphere and the effects of oblateness have been included.

 A Catalogue of Eclipse Cycles   (Site not responding. Last check: 2007-10-29)
Solar eclipses in an odd-numbered Saros series occur near the ascending node of the lunar orbit: they start with a small partial eclipse in the northern polar regions and slowly progress southwards, ending with a small partial eclipse in the southern polar regions.
Solar eclipses in an even-numbered Saros series occur near the descending node of the lunar orbit: they start with a small partial eclipse in the southern polar regions and slowly progress northwards, ending with a small partial eclipse in the northern polar regions.
Rules the regularity of lunar eclipse tetrads (four successive lunar eclipses that are all total and occur at intervals of six lunations) and solar eclipse duos (two solar eclipses at an interval of one lunation).

However for the sun who's distance from the earth changes throughout the year, the shape of the analemma (figure eight on globes and sundials) embodies what is known as the equation of time for an example how this rate varies with time.
The duration of an eclipse-season results from the fact that the sun's eclipse zone is 37 degrees or within 18.5 degrees of the node (point on orbital plane where moon crosses).
However, because the moon's eclipse zone is 12.25 degree from the node (or 24.5 degrees wide) and it takes 30.616 degrees for the moon to travel to its nodal position a synodic month later, the moon cannot have more than one partial or total eclipse during a three eclipse-season.

Eclipse cycles are important due to their influence in tidal cycles experienced on the Earth rather than the phenomenon of eclipses themselves.
However, this is not an eclipse cycle and requires the addition of 0.5 synodic month to attain the desired cycle of 99.5 synodic months.

 Definition of Eclipse cycle
The reason is that the orbit of the Moon precesses backward with respect to the ecliptic, and makes a full circle in somewhat less than 9 years.
The period to return to the same node is called eclipse year, and is about 1/9th year shorter than a sidereal year because of the precession of the nodes of the Moon's orbit in about 9 years.
12 months (a lunar year) is a little longer than an eclipse year: the Sun has returned to the node, so more eclipses may occur.

 BookPage Nonfiction Review: 1831: Year of Eclipse
The full eclipse of the sun that occurred on February 12 had been widely heralded, and so was not the fright that some earlier eclipses had been.
It was, for example, the year of the visit of Alexis de Tocqueville, the pre-eminent observer of America, who, like many other foreigners, saw civil war as inevitable.
It was the year that a more caustic English observer, Frances Trollope, left the country, liking nothing and scorning in particular the "vehement expressions of insane or hypocritical zeal" offered by itinerant preachers -- for which another modern parallel might be the scarifying nutcases infesting the "paid programming" recesses of television.

Masur's inability to directly tie the eclipse into the events of 1831 and the surrounding years, however, should not distract the reader from this well researched and informative description of the changes taking place in the United States.
1831 was a watershed year, a year in which some sluices were opened and others closed, a time when the roiling waters of liberty and democracy were undermining the foundations of elites, when the promises of revolutionary America were being extended to, revoked from, or taken up focibly by its people.
It is a fascinating time, and "1831 Year of Eclipse" lays out the key events of this era with admirable clarity.

But wars and economic disasters are not our only pivotal events, and other years have, in a quieter way, swayed the course of our nation.
The year began with a solar eclipse, for many an omen of mighty changes — and for once, such predictions held true.
As Masur's analysis makes clear, by 1831 it was becoming all too certain that political rancor, the struggle over slavery, the pursuit of individualism, and technological development might eclipse the glorious potential of the early republic--and lead the nation to secession and civil war.

(This includes total and annular-total eclipses.) If you were able to position yourself on the Earth at the point of maximum eclipse for each of these events, and you were blessed by clear skies during totality, you could spend a total of about 95 minutes in the shadow of the Moon.
