December 1983 lunar eclipse

A penumbral lunar eclipse took place on December 20, 1983. At the maximum eclipse, 89% of the Moon’s disk was partially shaded by the Earth, which caused a slight shadow gradient across its disc; this subtle effect may have been visible to careful observers. No part of the Moon was in complete shadow. The eclipse lasted 4 hours and 2 minutes overall.[1]

gollark: I mean, potatOS does horrible accursed things to Lua.
gollark: Nope.
gollark: Of course they would do horrible accursed C things. That is the point of C.
gollark: You're obviously saying that to distract us from how you wrote it.
