August 1989 Lunar Eclipse
A total lunar eclipse took place at 0308 UT (GMT) on Thursday, August 17, 1989, the second of two total lunar eclipses in 1989. The moon passed through the center of the Earth's shadow. Visibility It was seen completely over South America, and rising over North America, and setting over Africa, and Europe. : Relations to other lunar eclipses Eclipses of 1989 * A total lunar eclipse on February 20. * A partial solar eclipse on March 7. * A total lunar eclipse on August 17. * A partial solar eclipse on August 31. Lunar year series This eclipse is the second of four lunar year eclipses occurring at the moon's ascending node. The lunar year series repeats after 12 lunations or 354 days (Shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events. Saros series Lunar Saros 128 contains 15 total lunar eclipses between 1845 and 2097 (in years 1845, 1863, 1881, 1899, 1917, 1935, 19 ...

Metonic Cycle
The Metonic cycle or enneadecaeteris (from grc, ἐννεακαιδεκαετηρίς, from ἐννεακαίδεκα, "nineteen") is a period of almost exactly 19 years after which the lunar phases recur at the same time of the year. The recurrence is not perfect, and by precise observation the Metonic cycle defined as 235 lunar month, synodic months is just 2 hours, 4 minutes and 58 seconds longer than 19 tropical year, tropical years. Meton of Athens, in the 5th century BC, judged the cycle to be a whole number of days, 6,940. Using these whole numbers facilitates the construction of a lunisolar calendar. A tropical year is longer than 12 lunar months and shorter than 13 of them. The arithmetic identity 12×12 + 7×13 = 235 shows that a combination of 12 "short" years (12 months) and 7 "long" years (13 months) will be almost exactly equal to 19 solar years.

Solar Eclipse Of August 22, 1998
An annular solar eclipse occurred at the Moon’s ascending node of the orbit on August 22, 1998. 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 Indonesia, Malaysia, Papua New Guinea, Solomon Islands (Bellona Island and Rennell Island) and Vanuatu. Occurring only 5.2 days before apogee (Apogee on August 27, 1998), the Moon’s apparent diameter was 3.6% smaller than average.

Solar Eclipse Of August 10, 1980
An annular solar eclipse occurred at the Moon's ascending node of the orbit on August 10, 1980, centred over the Pacific Ocean.

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).

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 Saros 135
Saros cycle series 135 for solar eclipses occurs at the Moon's ascending node, repeating every 18 years, 11 days. Solar Saros 135 contains 71 events in which of 18 will be partial eclipses and 53 will be umbral eclipses (45 annular, 2 hybrid, 6 total). All eclipses in this series occurs at the Moon's ascending node. This solar saros is linked to Lunar Saros 128. On Monday, December 24, 1601, was the smallest annular solar eclipse in the 2nd millennium, with an eclipse magnitude of only 0.90785, just 0.002% larger than the solar eclipse of November 12, 1683 BC, was the smallest annular solar eclipse of thousands of years, with an eclipse magnitude of only 0.90783. The solar eclipse of January 15, 1638, was an annular solar eclipse of Solar Saros 135 that occurred only 43 minutes before apogee. The longest annular solar eclipse on the 2nd millennium was on December 14, 1955 (Saros 141), with a duration of 12 minutes, 9.17 seconds, while the smallest annular solar eclipse on ...
