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]

gollark: Weaponization of the sun via Nicoll-Dyson beam WHEN?!
gollark: No, you require there to not be too much UV, regardless of how that's provided.
gollark: That's not "required" as much as "extremely nice to have".
gollark: Well, doing enjoyable things is π important where π = 22.
gollark: Less if you ascend™ and upload your mind to the osmarks.tk™ computing clusters.
