October 1987 lunar eclipse

A penumbral lunar eclipse took place on October 7, 1987. The Moon approached within 1% of the Earth's umbral shadow at maximum eclipse; 99% 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.[1]

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 partial solar eclipses of Solar Saros 153.

gollark: I think you can still buy a few of them.

gollark: Arbitrary CPUs can and will be compared, bee.

gollark: They did for a bit. It wasn't very good.

gollark: I think modern ARM processors do micro-opy things too now.

gollark: You can count things like branch mispredicts.
