As already outlined in the tag, this was a drawing I did in 1972, so I was matching it up with the satellites in WinJupos as I did not know which moons/shadows they were. Of course the planetary details cannot be replicated with one of these generators, but I was surprised that the Red Spot was properly placed even with all the drifting it has done, looks like the program takes that into account, remarkable.

Looks like Europa was also in front of Jupiter at the same time, but was essentially camouflaged, and although the shadow of Europa is shown to be rather small. usually they really appear larger than the diagrams indicates, thus it shows rather large in the drawing.
