Juse moments ago...
Thought I was a seasoned observor, looked like a beautiful shadow transit close to the Great Red Spot. But checking SkySafari it was Ganymede!
Perhaps exactly what I was seeing as is a huge moon. Any verification Appreciated! Was a disturbance closer to GRS as well.
Past have spotted Jupiter moons entering, usually difficulty seeing them cross my usual experience.
Maybe I got up too early and seeing things, Lol!
Thanks for any reply in advance.
