May 1985 Lunar Eclipse
A total lunar eclipse took place on Saturday, May 4, 1985, the first of two total lunar eclipses in 1985, the second being on October 28, 1985. This lunar eclipse is first of a ''tetrad'', four total lunar eclipses in series. The last series was in 1967 and 1968, starting with an April 1967 lunar eclipse, while the next was in 2003 and 2004, starting with a May 2003 lunar eclipse. Visibility It is seen rising over the whole of Africa, Middle East, Europe and Asia. The eclipse was sighted over the Philippines at night. The second also followed on October 28, 1985.

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 Of May 10, 1994
An annular solar eclipse occurred at the moon's descending node of the orbit on Tuesday, May 10, 1994. It was visible over a wide swath of North America, from Baja California across the Midwest of the United States up through Ontario and Nova Scotia in Canada. Occurring only 1.6 days after apogee (Perigee on Monday, May 9, 1994 at 02:18 UTC or Sunday, May 8, 1994 at 22:18 EDT or 19:18 PDT), the moon's apparent diameter was smaller. This solar eclipse belonged to Saros series 128 because occurred at the Moon's descending node and 128 is an even number. The Annular Eclipse of May 10, 1994 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. The eclipse is either total or annular. In a total eclipse, the moon's size from earth is large enough to block all of the disk of the sun. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Eclipse Of April 29, 1976
An annular solar eclipse occurred at the Moon's descending node of the orbit on Thursday, April 29, 1976. 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 North Africa, Greece, Turkey, Middle East, central Asia, India, China. 5 of the 14 eight-thousanders in Pakistan and China—Nanga Parbat, K2, Broad Peak, Gasherbrum II and Gasherbrum I, lie in the path of annularity.

Solar Saros 128
Saros cycle series 128 for 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 month ...s occurs at the Moon's descending node, repeating every 18 years, 11 days, containing 73 events. All eclipses in this series occurs at the Moon's descending node. This solar saros is linked to Lunar Saros 121. 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 128 appears in the following table.

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.

List Of Lunar Eclipses In Saros Series 121
Saros cycle series 121 for lunar eclipses occurs at the moon's descending node. It began in 1029 and will end in 2526. It contains 84 member lunar eclipses, each separated by 18 years 11 and 1/3 days, and will last 1496.5 years. The series contains 29 total lunar eclipses between 1560 and 2021. It contains seven partial eclipses from 1398 to 1490 and seven more between 2039 and 2147. The last occurrence of this series was the last total lunar eclipse on May 2021 lunar eclipse, May 26, 2021. The next occurrence on June 2039 lunar eclipse, June 6, 2039 will be the first partial lunar eclipse, second set of partial lunar eclipses of this series. The longest totality occurred at series member 26, on October 18, 1660, lasting 102 minutes. This lunar saros is linked to Solar Saros 128.
