April 1958 lunar eclipse
A penumbral lunar eclipse took place on Friday, April 4, 1958, the first of three lunar eclipses in 1958. This was the last penumbral lunar eclipse of Saros cycle 102. In this extremely marginal eclipse, the Moon barely clipped the edge of the Earth's penumbral shadow. This caused a microscopic darkening of just 1% of the Moon's disc for 31 minutes exactly, which was essentially impossible to see.[1]

gollark: What are the axes?
gollark: Well, your graph looks very graphical, I suppose.
gollark: Yes. It might not be possible to do anything but somehow optimize the genetic-algorithm-based approach then.
gollark: That sounds worrying.
gollark: If your problem actually is nice and differentiable - which it sounds like it *might* be, I think you're laying out cables or something? - then it should be a lot faster if you can use that instead of just moving around randomly.
