Bet you missed it, didn't you? Unless you're Superman, you most certainly did: it was on Ganymede, a moon of Jupiter. Io moved between that moon and the sun casting a distinct shadow. I wonder in the great scheme of nomenclature if, as viewed from earth, this would be called a lunar eclipse? Probably best called an Ionian (Ionic?) eclipse. Whatever, very cool GIF animation from SpaceWeather.
