A total lunar eclipse took place on Thursday, April 24, 1986, the first of two total lunar eclipses in 1986, the second being on October 17, 1986. The Moon was plunged into darkness for 1 hour, 3 minutes and 34.8 seconds, in a deep total eclipse which saw the Moon 20.217% of its diameter inside the Earth's umbral shadow. The visual effect of this depends on the state of the Earth's atmosphere, but the Moon may have been stained a deep red colour. The partial eclipse lasted for 3 hours, 18 minutes and 46.8 seconds in total. The Moon was just 1.2 days before perigee (Perigee on Friday, April 25, 1986), making it 5.3% larger than average.
Visibility
It is seen rising over eastern Asia, the Pacific Ocean, and western North America and South America, the eclipse is also seen setting over the whole of Europe, Africa and Western Asia. The eclipse was seen very visible over the Philippines, it becomes the first lunar eclipse after the EDSA Revolution since the two lunar eclipses happened between May 4, 1985 and October 28, 1985 and the second followed on October 17, 1986. It also followed on February 20, 1989.
Eclipses in 1986 are:
Partial Solar eclipse of April 9, 1986
Total Lunar Eclipse of April 24, 1986
Hybrid Solar eclipse of October 3, 1986
Total Lunar Eclipse of October 17, 1986 (October 1986 lunar eclipse)
It also followed the passage of Halley's comet in the same year.

Saros series
Lunar Saros series 131, has 72 lunar eclipses. Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.
This eclipse series began in AD 1427 with a partial eclipse at the southern edge of the Earth's shadow when the Moon was close to its descending node. Each successive Saros cycle, the Moon's orbital path is shifted northward with respect to the Earth's shadow, with the first total eclipse occurring in 1950. For the following 252 years, total eclipses occur, with the central eclipse being predicted to occur in 2078. The first partial eclipse after this is predicted to occur in the year 2220, and the final partial eclipse of the series will occur in 2707. The total lifetime of the lunar Saros series 131 is 1280 years. Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.
Because of the ⅓ fraction of days in a Saros cycle, the visibility of each eclipse will differ for an observer at a given fixed locale. For the lunar Saros series 131, the first total eclipse of 1950 had its best visibility for viewers in Eastern Europe and the Middle East because mid-eclipse was at 20:44 UT. The following eclipse in the series occurred approximately 8 hours later in the day with mid-eclipse at 4:47 UT, and was best seen from North America and South America. The third total eclipse occurred approximately 8 hours later in the day than the second eclipse with mid-eclipse at 12:43 UT, and had its best visibility for viewers in the Western Pacific, East Asia, Australia and New Zealand. This cycle of visibility repeats from the initiation to termination of the series, with minor variations. Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.
Lunar Saros series 131, repeating every 18 years and 11 days, has a total of 72 lunar eclipse events including 57 umbral lunar eclipses (42 partial lunar eclipses and 15 total lunar eclipses). Solar Saros 138 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

It is the third total lunar eclipse of the series. The next occurrence will be on May 4, 2004. The previous occurrence was April 13, 1968.
Metonic series
This eclipse is the third of four Metonic cycle lunar eclipses on the same date, April 23–24, each separated by 19 years:
The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will in nearly the same location relative to the background stars.

Half-Saros cycle
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[2] This lunar eclipse is related to two annular solar eclipses of Solar Saros 138.
