I along with Tony Schellinck, Paul Heath, Melody Hamilton and a group of others noticed the strange arrangement of the 4 Galilean moons - like butterfly wings. I made rough notes about this but couldn't find this particular lunar formation; the OH had no mention of it and SkySafariPro showed the moons in a line with Europa on one side and Io, Ganymede and Callisto on the other.
No explanation for this pattern. Perhaps Europa (upper right of the 4 sketched) formed the shape with three GAIA-designated stars and we didn't look further for the other 3 moons (?).
