October 1987 Lunar Eclipse
A penumbral lunar eclipse took place on Wednesday, October 7, 1987, the second of two lunar eclipses in 1987, the first being on April 14, 1987. The Moon approached within 0.00949% of its diameter outside of touching the Earth’s umbral shadow at maximum eclipse; 98.63% of the Moon's disc was partially shaded by the Earth, with the overall eclipse lasting 4 hours and 14 minutes. While less dramatic than a partial eclipse (as no part of the Moon was in complete shadow), a shading across the Moon should have been readily visible to observers. The Moon was just 3.1 days after perigee (Perigee on Sunday, October 4, 1987), making it 2.1% larger than average.

Lunar Eclipse
A lunar eclipse occurs when the Moon moves into the Earth's shadow. Such alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, which can happen only on the night of a full moon when the Moon is near either lunar node. The type and length of a lunar eclipse depend on the Moon's proximity to the lunar node. When the moon is totally eclipsed by the Earth, it takes on a reddish color that is caused by the planet when it completely blocks direct sunlight from reaching the Moon surface, as only the light reflected from the lunar surface has been refracted by Earth's atmosphere. This light appears reddish due to the Rayleigh scattering of blue light, the same reason sunrise and sunsets are more orange than during the day. ...

Solar Eclipse Of October 2, 1978
A partial solar eclipse occurred at the Moon's ascending node of the orbit on Monday, October 2, 1978. 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. The eclipse is a part of the 153 saros cycle. Its the 7th eclipse of the saros cycle.

Solar Eclipse Of October 12, 1996
A partial solar eclipse occurred on October 12, 1996. 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 Saros 153
Saros cycle series 153 for solar eclipses occurs at the Moon's ascending node An orbital node is either of the two points where an orbit intersects a plane of reference to which it is inclined. A non-inclined orbit, which is contained in the reference plane, has no nodes. Planes of reference Common planes of refere ..., repeating every 18 years, 11 days, containing 70 events, with 63 before 3000 AD. All eclipses in this series occurs at the Moon's ascending node. This solar saros is linked to Lunar Saros 146. 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 153 appears in the following table.

April 1987 Lunar Eclipse
A penumbral lunar eclipse took place on Tuesday, April 14, 1987, the first of two lunar eclipses in 1987, the second being on October 7, 1987. This subtle penumbral eclipse may have been visible to a skilled observer at maximum eclipse. 77.703% of the Moon's disc was partially shaded by the Earth (none of it was in total shadow), which caused a gentle shadow gradient across its disc at maximum; the eclipse as a whole lasted 3 hours, 54 minutes and 12.8 seconds. The Moon was just 4.6 days before perigee (Perigee on Saturday, April 18, 1987), making it 0.5% larger than average. Visibility It was completely visible over North America, South America, the Atlantic Ocean, Europe, Africa and west in Asia, seen rising over the Pacific Ocean and North America and setting over South Asia and the Indian Ocean. Member This is the 22nd member of Lunar Saros 141. The previous event was the April 1969 lunar eclipse. The next event is the April 2005 lunar eclipse. Related lunar eclipses ...

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 Eclipse Of September 23, 1987
An annular solar eclipse occurred on September 23, 1987. 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 the Soviet Union (today's Kazakhstan), China (including Shanghai), southwestern Mongolia, Okinawa Islands of Japan except Kume Island and the southwestern tip of Kerama Islands, the Federal States of Micronesia, Papua New Guinea, Solomon Islands, Rotuma Islands of Fiji, Wallis Islands and West Samoa (the name changed to Samoa later). Occurring only 5 days after apogee (Apogee on September 18, 1987), the Moon's apparent diameter was relatively small. Observation Five r ...
